Subject: [PATCH 001/793] JFS: commit_mutex cleanups
I look at code, and see that
1)locks wasn't release in the opposite order in which they were taken
2)in jfs_rename we lock new_ip, and in "error path" we didn't unlock it
3)I see strange expression: "! !"
May be this worth to fix?

Subject: [PATCH 002/793] e1000: prevent statistics from garbling during bus
resets
If a PCI bus error/fault triggers a PCI bus reset, attempts to get
the ethernet packet count statistics from the hardware will fail,
returning garbage data upstream. This patch skips statistics data
collection if the PCI device is not on the bus.

Ethtool was reporting that loopback failed randomly on esb2
systems. Upon study it was found that the phy manual was changed
with respect to the loopback mode bits. The new value fixes it.

Subject: [PATCH 004/793] e1000: rework driver hardware reset locking
After studying the driver mac reset code it was found that there
were multiple race conditions possible to reset the unit twice or
bring it e1000_up() double. This fixes all occurences where the
driver needs to reset the mac.
We also remove irq requesting/releasing into _open and _close so
that while the device is _up we will never touch the irq's. This fixes
the double free irq bug that people saw.
To make sure that the watchdog task doesn't cause another race we let
it run as a non-scheduled task.

Subject: [PATCH 005/793] e1000: Make PHY powerup/down a function
In relation to the irq work done earlier we also move the PHY powerup
and powerdown functions into separate functions and move the calls to
_close and _open, making the PHY stay in it's power state as long as
the device is _up.

Subject: [PATCH 012/793] e1000: force register write flushes to circumvent
broken platforms
A certain AMD64 bridge (8132) has an option to turn on write combining
which breaks our adapter. To circumvent this we need to flush every write.

Subject: [PATCH 020/793] e1000: allow user to disable ich8 lock loss
workaround
The workaround for the ich8 lock loss problem is only needed for
a very small amount of systems. This adds an option for the user
to disable the workaround.

-
- 0.99H+lk0.9 - David S. Miller - softnet, PCI DMA updates
- 0.99H+lk1.0 - Jeff Garzik <jgarzik@pobox.com>
- Remove compatibility defines for kernel versions < 2.2.x.
- Update for new 2.3.x module interface
- LK1.1.2 (March 19, 2000)
- * New PCI interface (jgarzik)
-
- LK1.1.3 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
- - Merged with 3c575_cb.c
- - Don't set RxComplete in boomerang interrupt enable reg
- - spinlock in vortex_timer to protect mdio functions
- - disable local interrupts around call to vortex_interrupt in
- vortex_tx_timeout() (So vortex_interrupt can use spin_lock())
- - Select window 3 in vortex_timer()'s write to Wn3_MAC_Ctrl
- - In vortex_start_xmit(), move the lock to _after_ we've altered
- vp->cur_tx and vp->tx_full. This defeats the race between
- vortex_start_xmit() and vortex_interrupt which was identified
- by Bogdan Costescu.
- - Merged back support for six new cards from various sources
- - Set vortex_have_pci if pci_module_init returns zero (fixes cardbus
- insertion oops)
- - Tell it that 3c905C has NWAY for 100bT autoneg
- - Fix handling of SetStatusEnd in 'Too much work..' code, as
- per 2.3.99's 3c575_cb (Dave Hinds).
- - Split ISR into two for vortex & boomerang
- - Fix MOD_INC/DEC races
- - Handle resource allocation failures.
- - Fix 3CCFE575CT LED polarity
- - Make tx_interrupt_mitigation the default
-
- LK1.1.4 25 April 2000, Andrew Morton <andrewm@uow.edu.au>
- - Add extra TxReset to vortex_up() to fix 575_cb hotplug initialisation probs.
- - Put vortex_info_tbl into __devinitdata
- - In the vortex_error StatsFull HACK, disable stats in vp->intr_enable as well
- as in the hardware.
- - Increased the loop counter in issue_and_wait from 2,000 to 4,000.
-
- LK1.1.5 28 April 2000, andrewm
- - Added powerpc defines (John Daniel <jdaniel@etresoft.com> said these work...)
- - Some extra diagnostics
- - In vortex_error(), reset the Tx on maxCollisions. Otherwise most
- chips usually get a Tx timeout.
- - Added extra_reset module parm
- - Replaced some inline timer manip with mod_timer
- (Franois romieu <Francois.Romieu@nic.fr>)
- - In vortex_up(), don't make Wn3_config initialisation dependent upon has_nway
- (this came across from 3c575_cb).
-
- LK1.1.6 06 Jun 2000, andrewm
- - Backed out the PPC defines.
- - Use del_timer_sync(), mod_timer().
- - Fix wrapped ulong comparison in boomerang_rx()
- - Add IS_TORNADO, use it to suppress 3c905C checksum error msg
- (Donald Becker, I Lee Hetherington <ilh@sls.lcs.mit.edu>)
- - Replace union wn3_config with BFINS/BFEXT manipulation for
- sparc64 (Pete Zaitcev, Peter Jones)
- - In vortex_error, do_tx_reset and vortex_tx_timeout(Vortex):

Subject: [PATCH 024/793] [PATCH] 8139too deadlock fix
> stack backtrace:
> [<f9099d31>] rtl8139_start_xmit+0xd9/0xff [8139too]
> [<c11ad5ea>] netpoll_send_skb+0x98/0xea
This seems to be a real deadlock...
So netpoll_send_skb takes the _xmit_lock, which is all nitty gritty
but then rtl8139_start_xmit comes around while that lock is taken, and
does
spin_unlock_irq(&tp->lock);
which.. enables interrupts and softirqs; this is quite bad because the
xmit lock is taken in softirq context for the watchdog like this:
[<c1200376>] _spin_lock+0x23/0x32
[<c11af282>] dev_watchdog+0x14/0xb1
[<c101dab2>] run_timer_softirq+0xf2/0x14a
[<c101a691>] __do_softirq+0x55/0xb0
[<c1004a8d>] do_softirq+0x58/0xbd
Which would deadlock now that the spin_unlock_irq() has enabled
irqs/softirqs while the _xmit_lock is still held.
The patch below turns this into a irqsave/irqrestore pair so that
interrupts don't get enabled unconditionally.

make sure the cpu hotplug recursive mutex (yuck) is taken early in the
cpufreq codepaths to avoid a AB-BA deadlock.

Subject: [PATCH 033/793] [ATM]: fix possible recursive locking in
skb_migrate()
ok this is a real potential deadlock in a way, it takes two locks of 2
skbuffs without doing any kind of lock ordering; I think the following
patch should fix it. Just sort the lock taking order by address of the
skb.. it's not pretty but it's the best this can do in a minimally
invasive way.

drivers/net/irda/ali-ircc.c:ali_ircc_init()
The Coverity checker spotted, that from the changes from commit
898b1d16f8230fb912a0c2248df685735c6ceda3 the
if (ret)
platform_driver_unregister(&ali_ircc_driver);
was dead code.
This patch changes this function to what seems to have been the
intention.

Subject: [PATCH 035/793] [NET] gso: Add skb_is_gso
This patch adds the wrapper function skb_is_gso which can be used instead
of directly testing skb_shinfo(skb)->gso_size. This makes things a little
nicer and allows us to change the primary key for indicating whether an skb
is GSO (if we ever want to do that).

Subject: [PATCH 036/793] [NET] gso: Fix up GSO packets with broken checksums
Certain subsystems in the stack (e.g., netfilter) can break the partial
checksum on GSO packets. Until they're fixed, this patch allows this to
work by recomputing the partial checksums through the GSO mechanism.
Once they've all been converted to update the partial checksum instead of
clearing it, this workaround can be removed.

Subject: [PATCH 039/793] i386: improve and correct inline asm memory
constraints
Use "+m" rather than a combination of "=m" and "m" for improved clarity
and consistency.
This also fixes some inlines that incorrectly didn't tell the compiler
that they read the old value at all, potentially causing the compiler to
generate bogus code. It appear that all of those potential bugs were
hidden by the use of extra "volatile" specifiers on the data structures
in question, though.

Subject: [PATCH 041/793] [SCSI] scsi_transport_sas: add unindexed ports
Some SAS HBAs don't want to go to the trouble of tracking port numbers,
so they'd simply like to say "add this port and give it a number".
This is especially beneficial from the hotplug point of view, since
tracking ports and the available number space can be a real pain.
The current implementation uses an incrementing number per expander to
add the port on. However, since there can never be more ports than
there are phys, a later implementation will try to be more intelligent
about this.

Subject: [PATCH 043/793] [SCSI] mptsas: use unnumbered port API and remove
driver porttracking
This allows us to be rid of the machinery in mptsas for creating and
tracking port numbers. Since mptsas is merely inventing the numbers,
the SAS transport class may as well do it instead.

Misc Fixes:
- Fix some sparse warnings - casts of address space
- Fix handling of the adapter registration string. Each invocation
was byteswapping, so every other adapter init attempt failed.
- Correct comments and default value for the lpfc_max_luns parameter

probe
Without this patch we register an interrupt with request_irq,
but then return a bad return code from the module probe.

Subject: [PATCH 065/793] [SCSI] hide EH backup data outside the scsi_cmnd
Currently struct scsi_cmnd has various fields that are used to backup
original data after the corresponding fields have been overridden for
EH commands. This means drivers can easily get at it and misuse it.
Due to the old_ naming this doesn't happen for most of them, but two
that have different names have been used wrong a lot (see previous
patch). Another downside is that they unessecarily bloat the scsi_cmnd
size.
This patch moves them onstack in scsi_send_eh_cmnd to fix those two
issues aswell as allowing future EH fixes like moving the EH command
submissions to use SG lists like everything else.

From: Bob Moore <robert.moore@intel.com>
Date: Fri, 7 Jul 2006 20:44:38 -0400
Subject: [PATCH 069/793] ACPI: ACPICA 20060707
Added the ACPI_PACKED_POINTERS_NOT_SUPPORTED macro to
support C compilers that do not allow the initialization
of address pointers within packed structures - even though
the hardware itself may support misaligned transfers. Some
of the debug data structures are packed by default to
minimize size.
Added an error message for the case where
acpi_os_get_thread_id() returns zero. A non-zero value is
required by the core ACPICA code to ensure the proper
operation of AML mutexes and recursive control methods.
The DSDT is now the only ACPI table that determines whether
the AML interpreter is in 32-bit or 64-bit mode. Not really
a functional change, but the hooks for per-table 32/64
switching have been removed from the code. A clarification
to the ACPI specification is forthcoming in ACPI 3.0B.
Fixed a possible leak of an Owner ID in the error
path of tbinstal.c acpi_tb_init_table_descriptor() and
migrated all table OwnerID deletion to a single place in
acpi_tb_uninstall_table() to correct possible leaks when using
the acpi_tb_delete_tables_by_type() interface (with assistance
from Lance Ortiz.)
Fixed a problem with Serialized control methods where the
semaphore associated with the method could be over-signaled
after multiple method invocations.
Fixed two issues with the locking of the internal
namespace data structure. Both the Unload() operator and
acpi_unload_table() interface now lock the namespace during
the namespace deletion associated with the table unload
(with assistance from Linn Crosetto.)
Fixed problem reports (Valery Podrezov) integrated: -
Eliminate unnecessary memory allocation for CreateXxxxField
http://bugzilla.kernel.org/show_bug.cgi?id=5426
Fixed problem reports (Fiodor Suietov) integrated: -
Incomplete cleanup branches in AcpiTbGetTableRsdt (BZ 369)
- On Address Space handler deletion, needless deactivation
call (BZ 374) - AcpiRemoveAddressSpaceHandler: validate
Device handle parameter (BZ 375) - Possible memory leak,
Notify sub-objects of Processor, Power, ThermalZone (BZ
376) - AcpiRemoveAddressSpaceHandler: validate Handler
parameter (BZ 378) - Minimum Length of RSDT should be
validated (BZ 379) - AcpiRemoveNotifyHandler: return
AE_NOT_EXIST if Processor Obj has no Handler (BZ (380)
- AcpiUnloadTable: return AE_NOT_EXIST if no table of
specified type loaded (BZ 381)

From ab8aa06a5c0b75974fb1949365cbb20a15cedf14 Mon Sep 17 00:00:00 2001
From: Len Brown <len.brown@intel.com>
Date: Fri, 7 Jul 2006 20:11:07 -0400
Subject: [PATCH 070/793] ACPI: acpi_os_get_thread_id() returns current
Linux mutexes and the debug code that that reference
acpi_os_get_thread_id() are happy with 0.
But the AML mutexes in exmutex.c expect a unique non-zero
number for each thread - as they track this thread_id
to permit the mutex re-entrancy defined by the ACPI spec.

Subject: [PATCH 072/793] [SERIAL] IP22: fix serial console hangs
The patch below fixes serial console hangs as seen on IP22
machines. Typically, while booting, the machine hangs for ~1 minute
displaying "INIT: ", then the same thing happens again when init
enters in the designated runlevel and finally the getty process on
ttyS0 hangs indefinitely (though strace'ing it helps).
strace (-e raw=ioctl, otherwise the ioctl() translation is utterly
bogus) reveals that getty hangs on ioctl() 0x540f which happens to be
TCSETSW (I saw it hang on another console ioctl() but couldn't
reproduce that one).
A diff between ip22zilog and sunzilog revealed the following
differences:
1. the channel A flag being set on up.port.flags instead of up.flags
2. the channel A flag being set on what is marked as being channel B
3. sunzilog has a call to uart_update_timeout(port, termios->c_cflag, baud);
at the end of sunzilog_set_termios(), which ip22zilog lacks (on
purpose ?)
The patch below addresses point 1 and fixes the serial console hangs
just fine. However point 2 should be investigated by someone familiar
with the IP22 Zilog; it's probably OK as is but even if it is, a
comment in ip22zilog.c is badly needed.
Point 3 is left as an exercise for whoever feels like digging into
ip22zilog :)
These are the main obvious differences between ip22zilog and
sunzilog. Newer versions of sunzilog (Linus's git tree as of today)
are more close to ip22zilog as the sbus_{write,read}b have been
changed into simple {write,read}b, which shrinks the diff by a fair
amount. Resyncing both drivers should be doable in a few hours time
now for someone familiar with the IP22 Zilog hardware.

Subject: [PATCH 073/793] [SERIAL] 8250: add tsi108 serial support
The following patch gets rid of CONFIG_TSI108_BRIDGE. I add UPIO_TSI to
handle IIR and IER register in serial_in and serial_out.
(1) the reason to rewrite serial_in:
TSI108 rev Z1 version ERRATA. Reading the UART's Interrupt
Identification Register (IIR) clears the Transmit Holding Register
Empty (THRE) and Transmit buffer Empty (TEMP) interrupts even if they
are not enabled in the Interrupt Enable Register (IER). This leads to
loss of the interrupts. Interrupts are not cleared when reading UART
registers as 32-bit word.
(2) the reason to rewrite serial_out:
Check for UART_IER_UUE bit in the autoconfig routine. This section
of autoconfig is excluded for Tsi108/109 because bits 7 and 6 are
reserved for internal use. They are R/W bits. In addition to
incorrect identification, changing these bits (from 00) will make
Tsi108/109 UART non-functional.

From b3cf257623fabd8f1ee6700a6d328cc1c5da5a1d Mon Sep 17 00:00:00 2001
From: Stephane Eranian <eranian@hpl.hp.com>
Date: Sun, 9 Jul 2006 21:12:39 -0400
Subject: [PATCH 076/793] [PATCH] i386: use thread_info flags for debug regs
and IO bitmaps
Use thread info flags to track use of debug registers and IO bitmaps.
- add TIF_DEBUG to track when debug registers are active
- add TIF_IO_BITMAP to track when I/O bitmap is used
- modify __switch_to() to use the new TIF flags
Performance tested on Pentium II, ten runs of LMbench context switch
benchmark (smaller is better:)

Subject: [PATCH 081/793] ACPI: SBS: fix initialization, sem2mutex
cm_sbs_sem is being downed (via acpi_ac_init->acpi_lock_ac_dir) before it is
initialised, with grave results.
- Make it a mutex
- Initialise it
- Make it static
- Clean other stuff up.

Subject: [PATCH 082/793] ACPI: acpi_os_allocate() fixes
Replace acpi_in_resume with a more general hack
to check irqs_disabled() on any kmalloc() from ACPI.
While setting (system_state != SYSTEM_RUNNING) on resume
seemed more general, Andrew Morton preferred this approach.
http://bugzilla.kernel.org/show_bug.cgi?id=3469
Make acpi_os_allocate() into an inline function to
allow /proc/slab_allocators to work.
Delete some memset() that could fault on allocation failure.

Subject: [PATCH 083/793] [PATCH] splice: fix problems with sys_tee()
Several issues noticed/fixed:
- We cannot reliably block in link_pipe() while holding both input and output
mutexes. So do preparatory checks before locking down both mutexes and doing
the link.
- The ipipe->nrbufs vs i check was bad, because we could have dropped the
ipipe lock in-between. This causes us to potentially look at unknown
buffers if we were racing with someone else reading this pipe.

Subject: [PATCH 087/793] [PATCH] don't select CONFIG_HOTPLUG
It's useful to be able to turn off CONFIG_HOTPLUG for compile-coverage testing
and for section-checking coverage. But a few things go and select
CONFIG_HOTPLUG, making it a royal PITA to turn the thing off.
It's only turnable offable if CONFIG_EMBEDDED anyway. So let's make those
things depend on HOTPLUG, not select it.

Subject: [PATCH 090/793] [PATCH] sched: fix bug in __migrate_task()
Problem:
In the function __migrate_task(), deactivate_task() followed by
activate_task() is used to move the task from one run queue to
another. This has two undesirable effects:
1. The task's priority is recalculated. (Nowhere else in the
scheduler code is the priority recalculated for a change of CPU.)
2. The task's time stamp is set to the current time. At the very least,
this makes the adjustment of the time stamp before the call to
deactivate_task() redundant but I believe the problem is more serious
as the time stamp now holds the time of the queue change instead of
the time at which the task was woken. In addition, unless dest_rq is
the same queue as "current" is on the time stamp could be inaccurate
due to inter CPU drift.
Solution:
Replace the call to activate_task() with one to __activate_task().

Remove the conflict between fscontext and context mount options. If

both are specified we will use mount point labeling and all inodes will get
the label specified by context=. The superblock will be labeled with the
label of fscontext=, thus affecting operations which check the superblock
security context, such as associate permissions.

Subject: [PATCH 094/793] [PATCH] reiserfs: fix journaling issue regarding
fsync()
When write() extends a file(i_size is increased) and fsync() is called,
change of inode must be written to journaling area through fsync().
But,currently the i_trans_id is not correctly updated when i_size is
increased. So fsync() does not kick the journal writer.
Reiserfs_file_write() already updates the transaction when blocks are
allocated, but the case when i_size increases and new blocks are not added
is not correctly treated.
Following patch fix this bug.

- -------------

-To get the kernel into memory different approaches can be used. They
-depend on what facilities are available:
-3.1) Writing the kernel onto a floppy using dd:
- As always you can just write the kernel onto a floppy using dd,
- but then it's not possible to use kernel command lines at all.
- To substitute the 'root=' parameter, create a dummy device on any
- linux system with major number 0 and minor number 255 using mknod:
- mknod /dev/boot255 c 0 255
+3.) Boot Loader
+ ----------
- Then copy the kernel zImage file onto a floppy using dd:
+To get the kernel into memory different approaches can be used.
+They depend on various facilities being available:
- dd if=/usr/src/linux/arch/i386/boot/zImage of=/dev/fd0
- And finally use rdev to set the root device:
+3.1) Booting from a floppy using syslinux
- rdev /dev/fd0 /dev/boot255
+ When building kernels, an easy way to create a boot floppy that uses
+ syslinux is to use the zdisk or bzdisk make targets which use
+ and bzimage images respectively. Both targets accept the
+ FDARGS parameter which can be used to set the kernel command line.
- You can then remove the dummy device /dev/boot255 again. There
- is no real device available for it.
- The other two kernel command line parameters cannot be substi-
- tuted with rdev. Therefore, using this method the kernel will
- by default use RARP and/or BOOTP, and if it gets an answer via
- RARP will mount the directory /tftpboot/<client-ip>/ as its
- root. If it got a BOOTP answer the directory name in that answer
- is used.
+ e.g.
+ make bzdisk FDARGS="root=/dev/nfs"
+
+ Note that the user running this command will need to have
+ access to the floppy drive device, /dev/fd0
+
+ For more information on syslinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/
+
+ N.B: Previously it was possible to write a kernel directly to
+ a floppy using dd, configure the boot device using rdev, and
+ boot using the resulting floppy. Linux no longer supports this
+ method of booting.
+
+3.2) Booting from a cdrom using isolinux
+
+ When building kernels, an easy way to create a bootable cdrom that
+ uses isolinux is to use the isoimage target which uses a bzimage
+ image. Like zdisk and bzdisk, this target accepts the FDARGS
+ parameter which can be used to set the kernel command line.
+
+ e.g.
+ make isoimage FDARGS="root=/dev/nfs"
+
+ The resulting iso image will be arch/<ARCH>/boot/image.iso
+ This can be written to a cdrom using a variety of tools including
+ cdrecord.
+
+ e.g.
+ cdrecord dev=ATAPI:1,0,0 arch/i386/boot/image.iso
+
+ For more information on isolinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/
3.2) Using LILO
- When using LILO you can specify all necessary command line
- parameters with the 'append=' command in the LILO configuration
- file. However, to use the 'root=' command you also need to
- set up a dummy device as described in 3.1 above. For how to use
- LILO and its 'append=' command please refer to the LILO
- documentation.
+ When using LILO all the necessary command line parameters may be
+ specified using the 'append=' directive in the LILO configuration
+ file.
+
+ However, to use the 'root=' directive you also need to create
+ a dummy root device, which may be removed after LILO is run.
+
+ mknod /dev/boot255 c 0 255
+
+ For information on configuring LILO, please refer to its documentation.
3.3) Using GRUB
- When you use GRUB, you simply append the parameters after the kernel
- specification: "kernel <kernel> <parameters>" (without the quotes).
+ When using GRUB, kernel parameter are simply appended after the kernel
+ specification: kernel <kernel> <parameters>
3.4) Using loadlin
- When you want to boot Linux from a DOS command prompt without
- having a local hard disk to mount as root, you can use loadlin.
- I was told that it works, but haven't used it myself yet. In
- general you should be able to create a kernel command line simi-
- lar to how LILO is doing it. Please refer to the loadlin docu-
- mentation for further information.
+ loadlin may be used to boot Linux from a DOS command prompt without
+ requiring a local hard disk to mount as root. This has not been
+ thoroughly tested by the authors of this document, but in general
+ it should be possible configure the kernel command line similarly
+ to the configuration of LILO.
+
+ Please refer to the loadlin documentation for further information.
3.5) Using a boot ROM
- This is probably the most elegant way of booting a diskless
- client. With a boot ROM the kernel gets loaded using the TFTP
- protocol. As far as I know, no commercial boot ROMs yet
- support booting Linux over the network, but there are two
- free implementations of a boot ROM available on sunsite.unc.edu
- and its mirrors. They are called 'netboot-nfs' and 'etherboot'.
- Both contain everything you need to boot a diskless Linux client.
+ This is probably the most elegant way of booting a diskless client.
+ With a boot ROM the kernel is loaded using the TFTP protocol. The
+ authors of this document are not aware of any no commercial boot
+ ROMs that support booting Linux over the network. However, there
+ are two free implementations of a boot ROM, netboot-nfs and
+ etherboot, both of which are available on sunsite.unc.edu, and both
+ of which contain everything you need to boot a diskless Linux client.
3.6) Using pxelinux
- Using pxelinux you specify the kernel you built with
+ Pxelinux may be used to boot linux using the PXE boot loader
+ which is present on many modern network cards.
+
+ When using pxelinux, the kernel image is specified using
"kernel <relative-path-below /tftpboot>". The nfsroot parameters
are passed to the kernel by adding them to the "append" line.
- You may perhaps also want to fine tune the console output,
- see Documentation/serial-console.txt for serial console help.
+ It is common to use serial console in conjunction with pxeliunx,
+ see Documentation/serial-console.txt for more information.
+
+ For more information on isolinux, including how to create bootdisks
+ for prebuilt kernels, see http://syslinux.zytor.com/

Subject: [PATCH 098/793] [PATCH] partitions: let partitions inherit policy
from disk
Change the partition code in fs/partitions/check.c to initialize a newly
detected partition's policy field with that of the containing block device
(see patch below).
My reasoning is that function set_disk_ro() in block/genhd.c modifies the
policy field (read-only indicator) of a disk and all contained partitions.
When a partition is detected after the call to set_disk_ro(), the policy
field of this partition will currently not inherit the disk's policy field.
This behavior poses a problem in cases where a block device can be
'logically de- and reactivated' like e.g. the s390 DASD driver because
partition detection may run after the policy field has been modified.

Subject: [PATCH 103/793] [PATCH] lockdep: core, reduce per-lock class-cache
size
lockdep_map is embedded into every lock, which blows up data structure
sizes all around the kernel. Reduce the class-cache to be for the default
class only - that is used in 99.9% of the cases and even if we dont have a
class cached, the lookup in the class-hash is lockless.
This change reduces the per-lock dep_map overhead by 56 bytes on 64-bit
platforms and by 28 bytes on 32-bit platforms.

Subject: [PATCH 109/793] [PATCH] release_firmware() fixes
Use release_firmware() to free requested resources.
According to Documentation/firmware_class/README the request_firmware()
call should be followed by a release_firmware(). Some drivers do not
however free the firmware previously allocated with request_firmware().
This patch tries to fix this by making sure that release_firmware() is used
as expected.

Subject: [PATCH 112/793] [PATCH] vt: Remove VT-specific declarations and
definitions from tty.h
MAX_NR_CONSOLES, fg_console, want_console and last_console are more of a
function of the VT layer than the TTY one. Moving these to vt.h and vt_kern.h
allows all of the framebuffer and VT console drivers to remove their
dependency on tty.h.

From: Jon Smirl <jonsmir@gmail.com>
Date: Mon, 10 Jul 2006 04:44:13 -0700
Subject: [PATCH 113/793] [PATCH] tty: Remove include of screen_info.h from
tty.h
screen_info.h doesn't have anything to do with the tty layer and shouldn't be
included by tty.h. This patches removes the include and modifies all users to
directly include screen_info.h. struct screen_info is mainly used to
communicate with the console drivers in drivers/video/console. Note that this
patch touches every arch and I have no way of testing it. If there is a
mistake the worst thing that will happen is a compile error.

Subject: [PATCH 114/793] [PATCH] md: possible fix for unplug problem
I have reports of a problem with raid5 which turns out to be because the raid5
device gets stuck in a 'plugged' state. This shouldn't be able to happen as
3msec after it gets plugged it should get unplugged. However it happens
none-the-less. This patch fixes the problem and is a reasonable thing to do,
though it might hurt performance slightly in some cases.
Until I can find the real problem, we should probably have this workaround in
place.

Subject: [PATCH 115/793] [PATCH] md: set desc_nr correctly for version-1
superblocks
This has to be done in ->load_super, not ->validate_super
Without this, hot-adding devices to an array doesn't always
work right - though there is a work around in mdadm-2.5.2 to
make this less of an issue.

Subject: [PATCH 116/793] [PATCH] md: delay starting md threads until array is
completely setup
When an array is started we start one or two threads (two if there is a
reshape or recovery that needs to be completed).
We currently start these *before* the array is completely set up and in
particular before queue->queuedata is set. If the thread actually starts
very quickly on another CPU, we can end up dereferencing queue->queuedata
and oops.
This patch also makes sure we don't try to start a recovery if a reshape is
being restarted.

Subject: [PATCH 117/793] [PATCH] md: fix resync speed calculation for
restarted resyncs
We introduced 'io_sectors' recently so we could count the sectors that causes
io during resync separate from sectors which didn't cause IO - there can be a
difference if a bitmap is being used to accelerate resync.
However when a speed is reported, we find the number of sectors processed
recently by subtracting an oldish io_sectors count from a current
'curr_resync' count. This is wrong because curr_resync counts all sectors,
not just io sectors.
So, add a field to mddev to store the curren io_sectors separately from
curr_resync, and use that in the calculations.

Subject: [PATCH 118/793] [PATCH] md: fix a plug/unplug race in raid5
When a device is unplugged, requests are moved from one or two (depending on
whether a bitmap is in use) queues to the main request queue.
So whenever requests are put on either of those queues, we should make sure
the raid5 array is 'plugged'. However we don't. We currently plug the raid5
queue just before putting requests on queues, so there is room for a race. If
something unplugs the queue at just the wrong time, requests will be left on
the queue and nothing will want to unplug them. Normally something else will
plug and unplug the queue fairly soon, but there is a risk that nothing will.

Subject: [PATCH 122/793] [PATCH] md: require CAP_SYS_ADMIN for
(re-)configuring md devices via sysfs
The ioctl requires CAP_SYS_ADMIN, so sysfs should too. Note that we don't
require CAP_SYS_ADMIN for reading attributes even though the ioctl does.
There is no reason to limit the read access, and much of the information is
already available via /proc/mdstat

Subject: [PATCH 132/793] [PATCH] ACPI: fix fan/thermal resume
Daniel Ritz <daniel.ritz-ml@swissonline.ch> says:
The acpi driver suspend/resume patches that went in recently caused a regression
on my box (toshiba tecra 8000 laptop): after resume from swsusp the fan turns on
keeping blowing cold air out of my notebook. before the patches, the fan was off
and would only make noise when required. it's the same thing described in
bugzilla.kernel.org #5000. the acpi suspend/resume patches or at least parts of
them originate in this bug. now the last patch in the report (attach id 8438)
actually fixes the problem - for me and the reporter. this is a trimmed down
version of that patch.

Subject: [PATCH 133/793] [PATCH] pi-futex: Validate futex type instead of
oopsing
Calling futex_lock_pi is called with a reference to a non PI futex and
waiters exist already, lookup_pi_state() oopses due to pi_state == NULL.
Check this condition and return -EINVAL to userspace.

Subject: [PATCH 134/793] [PATCH] ZVC: add __inc_zone_state for !SMP
configuration
It turns out that there is a way to build a kernel with NUMA and no SMP.
In that case we are missing one definition __inc_zone_state.
Provide that missing __inc_zone_state.
(akpm: NUMA && !SMP sounds odd, but I am told "But there is the concept of
cpuless nodes. A NUMA system without SMP has a single processor but multiple
memory nodes. This used to work before on IA64 (wasn't aware of it, never seen
anyone with this kind of thing).")

A large number of lost ticks can cause an overadjustment of the clock. To
compensate for this we look at the current error and the larger the error
already is the more careful we are at adjusting the error. As small extra
fix reset the error when the clock is set.

Subject: [PATCH 140/793] [PATCH] aoa: fix when all is built into the kernel
This patch fixes initialisation issues when all of aoa is built into the
kernel by re-ordering the link order in the Makefile and making the soundbus
use subsys_initcall so it is initialised earlier.

Subject: [PATCH 145/793] [PATCH] aoa: tas: fix initialisation/reset
This patch fixes the initialisation and reset of the tas codec. The tas will
often reset if the i2s clocks go away so it needs to be completely
re-initialised when clocks come back.
Also, this patch adds some code for DRC that will be exploited later to add a
DRC control again, fixing a regression over snd-powermac.

The layout fabric gained support for all IDs when I extracted those from the
OSX description file. But apparently I had forgotten to add them all as
module aliases so the module will also load. This patch adds them.

Subject: [PATCH 149/793] [PATCH] powerpc: fix trigger handling in the new irq
code
This patch slightly reworks the new irq code to fix a small design error. I
removed the passing of the trigger to the map() calls entirely, it was not a
good idea to have one call do two different things. It also fixes a couple of
corner cases.
Mapping a linux virtual irq to a physical irq now does only that. Setting the
trigger is a different action which has a different call.
The main changes are:
- I no longer call host->ops->map() for an already mapped irq, I just return
the virtual number that was already mapped. It was called before to give an
opportunity to change the trigger, but that was causing issues as that could
happen while the interrupt was in use by a device, and because of the
trigger change, map would potentially muck around with things in a racy way.
That was causing much burden on a given's controller implementation of
map() to get it right. This is much simpler now. map() is only called on
the initial mapping of an irq, meaning that you know that this irq is _not_
being used. You can initialize the hardware if you want (though you don't
have to).
- Controllers that can handle different type of triggers (level/edge/etc...)
now implement the standard irq_chip->set_type() call as defined by the
generic code. That means that you can use the standard set_irq_type() to
configure an irq line manually if you wish or (though I don't like that
interface), pass explicit trigger flags to request_irq() as defined by the
generic kernel interfaces. Also, using those interfaces guarantees that
your controller set_type callback is called with the descriptor lock held,
thus providing locking against activity on the same interrupt (including
mask/unmask/etc...) automatically. A result is that, for example, MPIC's
own map() implementation calls irq_set_type(NONE) to configure the hardware
to the default triggers.
- To allow the above, the irq_map array entry for the new mapped interrupt
is now set before map() callback is called for the controller.
- The irq_create_of_mapping() (also used by irq_of_parse_and_map()) function
for mapping interrupts from the device-tree now also call the separate
set_irq_type(), and only does so if there is a change in the trigger type.
- While I was at it, I changed pci_read_irq_line() (which is the helper I
would expect most archs to use in their pcibios_fixup() to get the PCI
interrupt routing from the device tree) to also handle a fallback when the
DT mapping fails consisting of reading the PCI_INTERRUPT_PIN to know wether
the device has an interrupt at all, and the the PCI_INTERRUPT_LINE to get an
interrupt number from the device. That number is then mapped using the
default controller, and the trigger is set to level low. That default
behaviour works for several platforms that don't have a proper interrupt
tree like Pegasos. If it doesn't work for your platform, then either
provide a proper interrupt tree from the firmware so that fallback isn't
needed, or don't call pci_read_irq_line()
- Add back a bit that got dropped by my main rework patch for properly
clearing pending IPIs on pSeries when using a kexec

Subject: [PATCH 151/793] [PATCH] powerpc: fix SMU driver interrupt mapping
The SMU driver tries to map an interrupt from the device-tree before the
interrupt controllers in the machine have been enumerated. This doesn't work
properly and cause machines like the Quad g5 to fail booting later on when
some drivers waits endlessly for an SMU request to complete. This is the
second problem preventing boot on the Quad g5. This fixes it and also makes
the SMU driver a bit more resilient to not having an interrupt.

Subject: [PATCH 153/793] [PATCH] powermac: Combined fixes for backlight code
This patch fixes several problems:
- pmac_backlight_key() is called under interrupt context, and therefore
can't use mutexes or semaphores, so defer the backlight level for
later, as it's not critical (original code by Aristeu S. Rozanski F.
<aris@valeta.org>).
- Add exports for functions that might be called from modules
- Fix Kconfig depdencies on PMAC_BACKLIGHT.
- Fix locking issues on calls from inside the driver (reported by
Aristeu S. Rozanski F., too)
- Fix wrong calculation of backlight values in some of the drivers
- Replace pmac_backlight_key_up/down by inline functions

Subject: [PATCH 154/793] [PATCH] pci: initialize struct pci_dev.error_state
The pci channel state is currently uninitialized, thus there are two ways
of indicating that "everything's OK": 0 and 1. This is a bit of a burden.
If a devce driver wants to check if the pci channel is in a working or a
disconnected state, the driver writer must perform checks similar to
if((pdev->error_state != 0) &&
(pdev->error_state != pci_channel_io_normal)) {
whatever();
}
which is rather akward. The first check is needed because stuct pci_dev is
inited to all-zeros. The scond is needed because the error recovery will
set the state to pci_channel_io_normal (which is not zero).
This patch fixes this awkwardness.

Subject: [PATCH 155/793] [PATCH] usb-storage: wait for URB to complete
We all failed to notice that Franck's recent update to usb-storage allowed
an URB to complete after its context data was no longer valid. This patch
(as746) makes the driver wait for the URB to complete whenever there's a
timeout.
Although timeouts in usb-storage are relatively uncommon, they do occur.
Without this patch the code in 2.6.18-rc1 will fault within an interrupt
handler, which is not nice at all.

Subject: [PATCH 156/793] [PATCH] mmap zero-length hugetlb file with PROT_NONE
to protect a hugetlb virtual area
Sometimes, applications need below call to be successful although
"/mnt/hugepages/file1" doesn't exist.
fd = open("/mnt/hugepages/file1", O_CREAT|O_RDWR, 0755);
*addr = mmap(NULL, 0x1024*1024*256, PROT_NONE, 0, fd, 0);
As for regular pages (or files), above call does work, but as for huge
pages, above call would fail because hugetlbfs_file_mmap would fail if
(!(vma->vm_flags & VM_WRITE) && len > inode->i_size).
This capability on huge page is useful on ia64 when the process wants to
protect one area on region 4, so other threads couldn't read/write this
area. A famous JVM (Java Virtual Machine) implementation on IA64 needs the
capability.

Subject: [PATCH 158/793] [PATCH] FRV: Fix FRV arch compile errors
Fix some FRV arch compile errors, including:
(*) Marking nr_kernel_pages as __meminitdata so that references to it end up
being properly calculated rather than being assumed to be in the small
data section (and thus calculated wrt the GP register). Not doing this
causes the linker to emit errors as the offset is too big to fit into the
load instruction.
(*) Move pm_power_off into an unconditionally compiled .c file as it's now
unconditionally accessed.
(*) Declare frv_change_cmode() in a header file rather than in a .c file, and
declare it asmlinkage.

Subject: [PATCH 159/793] [PATCH] NOMMU: Fix execution off of ramfs with mmap()
Fix execution through the FDPIC binfmt of programs stored on ramfs by
preventing the ramfs mmap() returning successfully on a private mapping of
a ramfs file. This causes NOMMU mmap to make a copy of the mapped portion
of the file and map that instead.
This could be improved by granting direct mapping access to read-only
private mappings for which the data is stored on a contiguous run of pages.
However, this is only likely to be the case if the file was extended with
truncate before being written.
ramfs is left to map the file directly for shared mappings so that SYSV IPC
and POSIX shared memory both still work.

Subject: [PATCH 160/793] [PATCH] FDPIC: Adjust the ELF-FDPIC driver to conform
more to the CodingStyle
Adjust the ELF-FDPIC binfmt driver to conform much more to the CodingStyle,
silly though it may be.
Further changes:
(*) Drop the casts to long for addresses in kdebug() statements (they're
unsigned long already).
(*) Use extra variables to avoid expressions longer than 80 chars by splitting
the statement into multiple statements and letting the compiler optimise
them back together.
(*) Eliminate duplicate call of ksize() when working out how much space was
actually allocated for the stack.
(*) Discard the commented-out load_shlib prototype and op pointer as this will
not be supported in ELF-FDPIC for the foreseeable future.

CONFIG_PM_STD_PARTITION=""
Matthew Wilcox notified me that CONFIG_PM_STD_PARTITION="/dev/hda2" in the
i386 defconfig wasn't a good idea (especially since it prevented booting
for him due to another bug).
This patch sets CONFIG_PM_STD_PARTITION="" in the i386 defconfig.

Subject: [PATCH 167/793] [PATCH] swsusp: do not use memcpy for snapshotting
memory
swsusp should not use memcpy for snapshotting memory, because on some
architectures memcpy may increase preempt_count (i386 does this when
CONFIG_X86_USE_3DNOW is set). Then, as a result, wrong value of preempt_count
is stored in the image.
Replace memcpy in copy_data_pages with an open-coded loop.

Subject: [PATCH 172/793] [PATCH] uml: clean up address space limits code
I was looking at the code of the UML and more precisely at the functions
set_task_sizes_tt and set_task_sizes_skas. I noticed that these 2 functions
take a paramater (arg) which is not used : the function is always called with
the value 0.
I suppose that this value might change in the future (or even can be
configured), so I added a constant in mem_user.h file.
Also, I rounded CONFIG_HOST_TASk_SIZE to a 4M.

Subject: [PATCH 173/793] [PATCH] uml: timer initialization cleanup
This cleans up the mess that is the timer initialization. There used to be
two timer handlers - one that basically ran during delay loop calibration and
one that handled the timer afterwards. There were also two sets of timer
initialization code - one that starts in user code and calls into the kernel
side of the house, and one that starts in kernel code and calls user code.
This eliminates one timer handler and consolidates the two sets of
initialization code.

Date: Mon, 10 Jul 2006 04:45:06 -0700
Subject: [PATCH 175/793] [PATCH] uml: fix static binary segfault
When UML is built as a static binary, it segfaults when run. The reason is
that a memory hole that is present in dynamic binaries isn't there in static
binaries, and it contains essential stuff.
This fix removes the code which maps some anonymous memory into that hole and
cleans up some related code.

Subject: [PATCH 177/793] [PATCH] uml: signal initialization cleanup
It turns out that init_new_thread_signals is always called with altstack == 1,
so we can eliminate the parameter.

Subject: [PATCH 183/793] [PATCH] uml: fix exitcall ordering bug
This fixes an exitcall ordering bug - calls to ignore_sigio_fd can come from
exitcalls that come after the sigio thread has been killed. This would cause
shutdown to hang or crash.
Fixed by having ignore_sigio_fd check that the thread is present before trying
to communicate with it.

Subject: [PATCH 194/793] [PATCH] Fix and enable EDAC sysfs operation
When EDAC was first introduced into the kernel it had a sysfs interface,
but due to some problems it was disabled in 2.6.16 and remained disabled in
2.6.17.
With feedback, several of the control and attribute files of that interface
had some good constructive feedback. PCI Blacklist/Whitelist was a major
set which has design issues and it has been removed in this patch. Instead
of storing PCI broken parity status in EDAC, it has been moved to the
pci_dev structure itself by a previous PCI patch. A future patch will
enable that feature in EDAC by utilizing the pci_dev info.
The sysfs is now enabled in this patch, with a minimal set of control and
attribute files for examining EDAC state and for enabling/disabling the
memory and PCI operations.
The Documentation for EDAC has also been updated to reflect the new state
of EDAC operation.

Subject: [PATCH 195/793] [PATCH] make valid_mmap_phys_addr_range() take a pfn
Newer ARMs have a 40 bit physical address space, but mapping physical
memory above 4G needs a special page table format which we (currently?) do
not use for userspace mappings, so what happens instead is that mapping an
address >= 4G will happily discard the upper bits and wrap.
There is a valid_mmap_phys_addr_range() arch hook where we could check for
>= 4G addresses and deny the mapping, but this hook takes an unsigned long
address:
static inline int valid_mmap_phys_addr_range(unsigned long addr, size_t size);
And drivers/char/mem.c:mmap_mem() calls it like this:
static int mmap_mem(struct file * file, struct vm_area_struct * vma)
{
size_t size = vma->vm_end - vma->vm_start;
if (!valid_mmap_phys_addr_range(vma->vm_pgoff << PAGE_SHIFT, size))
So that's not much help either.
This patch makes the hook take a pfn instead of a phys address.

Subject: [PATCH 201/793] [PATCH] LED Class support for Soekris net48xx
Add LED Class device support for the Soekris net48xx Error LED. Tested
only on a net4801, but should work on a net4826 as well. I'd love to find
a way of detecting a Soekris net48xx device but there is no DMI or any
Soekris-specific PCI devices.

Subject: [PATCH 203/793] [PATCH] pc8736x_gpio: fix re-modprobe errors: undo
region reservation
Fix module-init-func by repairing usage of platform_device_del/put in
module-exit-func. IOW, it imitates Ingo's 'mishaps' patch, which fixed the
module-init-func's undo handling.
Also fixes lack of release_region to undo the earlier registration.
Also starts to 'use a cdev' which was originally intended (its present in
scx200_gpio). Code compiles and runs, exhibits a lesser error than
previously. (re-register-chrdev fails)
Since I had to add "include <linux/cdev.h>", I went ahead and made 2
tweaks that fell into diff-context-window:
- remove include <linux/config.h> everyone's doing it
- copyright updates - current date is 'wrong'

- Switch from register_chrdev() to (register|alloc)_chrdev_region().
- use a cdev. This was intended for original patchset, but was
overlooked.
We use a single cdev for all pins (minor device-numbers), as gleaned
from cs5535_gpio, and in contrast to whats currently done in scx200_gpio
(which I'll fix soon)

Subject: [PATCH 205/793] [PATCH] snsc: switch from force_sig to kill_proc
Currently the snsc driver uses force_sig to send init a SIGPWR when the
system overheats. This patch switches it to kill_proc instead which has
the following advantages:
(1) gets rid of one of the last remaining tasklist_lock users
in modular code
(2) simplifies the snsc code significantly
The downside is that an init implementation could in theory block SIGPWR
and it would not get delivered. The sysvinit code used by all major
distributions doesn't do this and blocking this signal in init would be a
rather stupid thing to do.

Subject: [PATCH 206/793] [PATCH] disallow modular binfmt_elf32
Currently most architectures either always build binfmt_elf32 in the kernel
image or make it a boolean option. Only sparc64 and s390 allow to build it
modularly. This patch turns the option into a boolean aswell because elf
requires various symbols that shouldn't be available to modules. The most
urgent one is tasklist_lock whos export this patch series kills, but there
are others like force_sgi aswell.
Note that sparc doesn't allow a modular 32bit a.out handler either, and
that would be the more useful case as only few people want 32bit sunos
compatibility and 99.9% of all sparc64 users need 32bit linux native elf
support.

-What: remove EXPORT_SYMBOL(tasklist_lock)
-When: August 2006
-Files: kernel/fork.c
-Why: tasklist_lock protects the kernel internal task list. Modules have
- no business looking at it, and all instances in drivers have been due
- to use of too-lowlevel APIs. Having this symbol exported prevents
- moving to more scalable locking schemes for the task list.

Subject: [PATCH 211/793] [PATCH] lockdep: disable lock debugging when kernel
state becomes untrusted
Disable lockdep debugging in two situations where the integrity of the
kernel no longer is guaranteed: when oopsing and when hitting a
tainting-condition. The goal is to not get weird lockdep traces that don't
make sense or are otherwise undebuggable, to not waste time.
Lockdep assumes that the previous state it knows about is valid to operate,
which is why lockdep turns itself off after the first violation it reports,
after that point it can no longer make that assumption.
A kernel oops means that the integrity of the kernel compromised; in
addition anything lockdep would report is of lesser importance than the
oops.
All the tainting conditions are of similar integrity-violating nature and
also make debugging/diagnosing more difficult.

Subject: [PATCH 217/793] [TCP]: Remove TCP Compound
This reverts: f890f921040fef6a35e39d15b729af1fd1a35f29
The inclusion of TCP Compound needs to be reverted at this time
because it is not 100% certain that this code conforms to the
requirements of Developer's Certificate of Origin 1.1 paragraph (b).

- * TCP Vegas congestion control
- *
- * This is based on the congestion detection/avoidance scheme described in
- * Lawrence S. Brakmo and Larry L. Peterson.
- * "TCP Vegas: End to end congestion avoidance on a global internet."
- * IEEE Journal on Selected Areas in Communication, 13(8):1465--1480,
- * October 1995. Available from:
- * ftp://ftp.cs.arizona.edu/xkernel/Papers/jsac.ps
- *
- * See http://www.cs.arizona.edu/xkernel/ for their implementation.
- * The main aspects that distinguish this implementation from the
- * Arizona Vegas implementation are:
- * o We do not change the loss detection or recovery mechanisms of
- * Linux in any way. Linux already recovers from losses quite well,
- * using fine-grained timers, NewReno, and FACK.
- * o To avoid the performance penalty imposed by increasing cwnd
- * only every-other RTT during slow start, we increase during
- * every RTT during slow start, just like Reno.
- * o Largely to allow continuous cwnd growth during slow start,
- * we use the rate at which ACKs come back as the "actual"
- * rate, rather than the rate at which data is sent.
- * o To speed convergence to the right rate, we set the cwnd
- * to achieve the right ("actual") rate when we exit slow start.
- * o To filter out the noise caused by delayed ACKs, we use the
- * minimum RTT sample observed during the last RTT to calculate
- * the actual rate.
- * o When the sender re-starts from idle, it waits until it has
- * received ACKs for an entire flight of new data before making
- * a cwnd adjustment decision. The original Vegas implementation
- * assumed senders never went idle.
- *
- *
- * TCP Compound based on TCP Vegas

Subject: [PATCH 220/793] [PATCH] x86_64: Bring x86-64 ia32 emul in sync with
i386 on READ_IMPLIES_EXEC enabling
Currently ia32 binaries behave differently with respect to enabling
READ_IMPLIES_EXEC. On i386 a binary with the exec_stack flag set is
executed with READ_IMPLIES_EXEC enabled as well. The same binary
executes without READ_IMPLIES_EXEC on x86-64.
This causes binaries that work on i386 to fail on x86-64 which goes
somewhat against the whole 32 bit emulation idea.
It has been argued that READ_IMPLIES_EXEC should not be enabled at all
for binaries that have the exec_stack flag. Which is probably a valid
point. However until this is clarified I think x86-64 should behave the
same for ia32 binaries as i386.
The following patch brings x86-64 in sync with i386 for ia32 binaries.

Add it for P4 model 6 - reported to work and have a similar PMU to
earlier P4s.
Add an p4force=1 module override parameter for future use.
We had a discussion about that earlier - it's a trade off between the
PMU staying compatible or not. I think the force parameter is a
reasonable compromise.

Subject: [PATCH 230/793] [ARM] Allow Versatile to be built for AB and PB
If a configuration was chosen to support both the Versatile
AB and PB boards, the result would write to registers not
available on the PB version of the board. Resolve this by
using machine_is_xxx().
Also, for the CLCD, despite how the code looks, both the AB
and PB access the same location to control the clock rate -
it's just called something different between the two board
versions. Invent our own name for this location and use it
unconditionally.

Patch from Pavel Machek
From: Dirk Opfer <Dirk@Opfer-Online.de>
Fix ucb initialization on collie. Wrong frequency was used and that
led to things not working quite correctly. (I had to actually disable
checks in my tree to get it to boot). It now includes all the
neccessary parts to get it to compile :-).

Using the port_id for the channel is completely unnecessary since the
host_id/target_id are constructed to be globally unique. Also move
the mptsas driver on to virtual channel 1 for its raid devices.

Subject: [PATCH 239/793] [S390] subchannel register/unregister mutex.
Add a reg_mutex to prevent unregistering a subchannel before it has been
registered. Since 2.6.17, we've seen oopses in kslowcrw when a device is
found to be not operational during sense id when doing initial device
recognition; it is not clear yet why that particular problem was not (yet)
observed with earlier kernels...

futex_atomic_cmpxchg_inatomic has the same bug as the other
atomic futex operations: the operation needs to be done in the
user address space, not the kernel address space. Add the missing
sacf 256 & sacf 0.

Subject: [PATCH 242/793] [S390] xpram module parameter parsing.
The module parameters for xpram are not or in a wrong way parsed.
The xpram module uses the module_param_array directive with an int
parameter which causes the kernel to automatically parse the passed
numbers. This will cause errors if arguments are omitted or cause
wrong results if arguments have size qualifiers.
Use module_param_array with charp and parse the arguments later.

Subject: [PATCH 243/793] [S390] path grouping and path verifications fixes.
1. Multipath devices for which SetPGID is not supported are not handled well.
Use NOP ccws for path verification (sans path grouping) when SetPGID is not
supported.
2. Check for PGIDs already set with SensePGID on _all_ paths (not just the
first one) and try to find a common one. Moan if no common PGID can be
found (and use NOP verification). If no PGIDs have been set, use the css
global PGID (as before). (Rationale: SetPGID will get a command reject if
the PGID it tries to set does not match the already set PGID.)
3. Immediately before reboot, issue RESET CHANNEL PATH (rcp) on all chpids. This
will remove the old PGIDs. rcp will generate solicited CRWs which can be
savely ignored by the machine check handler (all other actions create
unsolicited CRWs).

Subject: [PATCH 245/793] Add PIIX4 APCI quirk for the 440MX chipset too
This is confirmed to fix a hang due to PCI resource conflicts with
setting up the Cardbus bridge on old laptops with the 440MX chipsets.
Original report by Alessio Sangalli, lspci debugging help by Pekka
Enberg, and trial patch suggested by Daniel Ritz:
"From the docs available i would _guess_ this thing is really similar
to the 82443BX/82371AB combination. at least the SMBus base address
register is hidden at the very same place (32bit at 0x90 in function
3 of the "south" brigde)"
The dang thing is largely undocumented, but the patch was corroborated
by Asit Mallick:
"I am trying to find the register information. 440MX is an integration of
440BX north-bridge without AGP and PIIX4E (82371EB). PIIX4 quirk
should cover the ACPI and SMBus related I/O registers."
and verified to fix the problem by Alessio.

Subject: [PATCH 247/793] [SCSI] NCR_D700: misc fixes (section and argument
ordering)
Apparently the D700 has had an argument ordering issue for quite a while
which can cause it to get the wrong scsi_id (I just got an unbootable
voyager system because of this). Hopefully this patch also fixes up all
the sectional mismatches within the driver.

Subject: [PATCH 264/793] [PATCH] Fix prctl privilege escalation and
suid_dumpable (CVE-2006-2451)
Based on a patch from Ernie Petrides
During security research, Red Hat discovered a behavioral flaw in core
dump handling. A local user could create a program that would cause a
core file to be dumped into a directory they would not normally have
permissions to write to. This could lead to a denial of service (disk
consumption), or allow the local user to gain root privileges.
The prctl() system call should never allow to set "dumpable" to the
value 2. Especially not for non-privileged users.
This can be split into three cases:
1) running as root -- then core dumps will already be done as root,
and so prctl(PR_SET_DUMPABLE, 2) is not useful
2) running as non-root w/setuid-to-root -- this is the debatable case
3) running as non-root w/setuid-to-non-root -- then you definitely
do NOT want "dumpable" to get set to 2 because you have the
privilege escalation vulnerability
With case #2, the only potential usefulness is for a program that has
designed to run with higher privilege (than the user invoking it) that
wants to be able to create root-owned root-validated core dumps. This
might be useful as a debugging aid, but would only be safe if the program
had done a chdir() to a safe directory.
There is no benefit to a production setuid-to-root utility, because it
shouldn't be dumping core in the first place. If this is true, then the
same debugging aid could also be accomplished with the "suid_dumpable"
sysctl.

When found, it is obvious. nfds calculated when allocating fdsets is

sysfs has a different i_mutex lock order behavior for i_mutex than the
other filesystems; sysfs i_mutex is called in many places with subsystem
locks held. At the same time, many of the VFS locking rules do not apply
to sysfs at all (cross directory rename for example). To untangle this
mess (which gives false positives in lockdep), we're giving sysfs inodes
their own class for i_mutex.

Subject: [PATCH 271/793] [PATCH] Make cpu_relax() imply barrier() on all
arches
During the recent discussion of taking 'volatile' off of the spinlock, I
noticed that while most arches #define cpu_relax() such that it implies
barrier(), some arches define cpu_relax() to be empty.
This patch changes the definition of cpu_relax() for frv, h8300, m68knommu,
sh, sh64, v850 and xtensa from an empty while(0) to the compiler barrier().

Subject: [PATCH 272/793] [PATCH] ide: fix Jmicron support
Prior to 2.6.18rc1 you could install with devices on a JMicron chipset
using the "all-generic-ide" option. As of this kernel the AHCI driver
grabs the controller and rams it into AHCI mode losing the PATA ports
and making CD drives and the like vanish. The all-generic-ide option
fails because the AHCI driver grabbed the PCI device and reconfigured
it.
To fix this three things are needed.
#1 We must put the chip into dual function mode
#2 The AHCI driver must grab only function 0 (already in your rc1 tree)
#3 Something must grab the PATA ports
The attached patch is the minimal risk edition of this. It puts the chip
into dual function mode so that AHCI will grab the SATA ports without
losing the PATA ports. To keep the risk as low as possible the third
patch adds the PCI identifiers for the PATA port and the FN check to the
ide-generic driver. There is a more featured jmicron driver on its way
but that adds risk and the ide-generic support is sufficient to install
and run a system.
The actual chip setup done by the quirk is the precise setup recommended
by the vendor.
(The JMB368 appears only in the ide-generic entry as it has no AHCI so
does not need the quirk)

When establishing a new circuit in nr_rx_frame the locks are taken in

harmless but triggers lockdep. Either way, reordering the code a
little solves the issue.

Subject: [PATCH 278/793] [TCP] tcp_highspeed: Fix AI updates.
I think there is still a problem with the AIMD parameter update in
HighSpeed TCP code.
Line 125~138 of the code (net/ipv4/tcp_highspeed.c):
/* Update AIMD parameters */
if (tp->snd_cwnd > hstcp_aimd_vals[ca->ai].cwnd) {
while (tp->snd_cwnd > hstcp_aimd_vals[ca->ai].cwnd &&
ca->ai < HSTCP_AIMD_MAX - 1)
ca->ai++;
} else if (tp->snd_cwnd < hstcp_aimd_vals[ca->ai].cwnd) {
while (tp->snd_cwnd > hstcp_aimd_vals[ca->ai].cwnd &&
ca->ai > 0)
ca->ai--;
In fact, the second part (decreasing ca->ai) never decreases since the
while loop's inequality is in the reverse direction. This leads to
unfairness with multiple flows (once a flow happens to enjoy a higher
ca->ai, it keeps enjoying that even its cwnd decreases)
Here is a tentative fix (I also added a comment, trying to keep the
change clear):

Subject: [PATCH 279/793] [IPV6]: Use ipv6_addr_src_scope for link address
sorting.
In the source address selection, the address must be sorted
from global to node-local.
But, ifp->scope is different from the scope for source address
selection.
2001::1 fe80::1 ::1
ifp->scope 0 0x02 0x01
ipv6_addr_src_scope(&ifp->addr) 0x0e 0x02 0x01
So, we need to use ipv6_addr_src_scope(&ifp->addr) for sorting.
And, for backward compatibility, addresses should be sorted from
new one to old one.

Subject: [PATCH 280/793] [IPCOMP]: Fix truesize after decompression
The truesize check has uncovered the fact that we forgot to update truesize
after pskb_expand_head. Unfortunately pskb_expand_head can't update it for
us because it's used in all sorts of different contexts, some of which would
not allow truesize to be updated by itself.
So the solution for now is to simply update it in IPComp.
This patch also changes skb_put to __skb_put since we've just expanded
tailroom by exactly that amount so we know it's there (but gcc does not).

Subject: [PATCH 281/793] [AX.25]: Optimize AX.25 socket list lock
Right now all uses of the ax25_list_lock lock are _bh locks but knowing
some code is only ever getting invoked from _bh context we can better.

desciptor count
There were some tso bugs that only showed up with heavy load and 16kB
pages that this patch fixes by making the driver's internal use count
of descriptors match the count that it was estimating it needed using
the DESC_NEEDED macro. This bug caused NETDEV_WATCHDOG resets aka
tx timeouts.

Subject: [PATCH 297/793] [Bluetooth] Let BT_HIDP depend on INPUT
This patch lets BT_HIDP depend on instead of select INPUT. This fixes
the following warning during an s390 build:
net/bluetooth/hidp/Kconfig:4:warning: 'select' used by config symbol
'BT_HIDP' refer to undefined symbol 'INPUT'
A dependency on INPUT also implies !S390 (and therefore makes the
explicit dependency obsolete) since INPUT is not available on s390.
The practical difference should be nearly zero, since INPUT is always
set to y unless EMBEDDED=y (or S390=y).

Subject: [PATCH 308/793] [PATCH] sky2: optimize receive restart
When the driver handles multiple packets per NAPI poll, it is
better to reload the receive ring, then tell the hardware. Otherwise,
under packet storm with flow control, the driver/hardware will degrade
down to one packet getting through per pause-exchange.
Likewise on transmit, don't wakeup until a little more than minimum
ring space is available.

Subject: [PATCH 312/793] [PATCH] scx200_acb: Fix the block transactions
The scx200_acb i2c bus driver pretends to support SMBus block
transactions, but in fact it implements the more simple I2C block
transactions. Additionally, it lacks sanity checks on the length
of the block transactions, which could lead to a buffer overrun.
This fixes an oops reported by Alexander Atanasov:

Fix the value returned by the i2c-powermac's master_xfer method.
It should return the number of messages processed successfully, but
instead returns the number of data bytes in the first (and only)
processed message.
Also explicitly mention the master_xfer convention so that future
implementations get it right directly.

Subject: [PATCH 320/793] [PATCH] hwmon: Fix for first generation Abit uGuru
chips
Now that the abituguru driver is seeing some more widespread testing
it has turned out that one the first generation of Abit uGuru
motherboards, with uGuru revision 1, the autodetect bank1 sensor type
code doesn't (always) work. This patch adds a module param to override
the autodetect, and it adds validity checks for the value of the 2
other autodetection override module params. An example of howto use
the new param can be found here:

Subject: [PATCH 323/793] [PATCH] USB: au1200: EHCI and OHCI fixes
I received an DBAU1200 eval kit from AMD a few days ago and tried to
enable the USB2 port, but the current linux-2.6 GIT did not even
compile with CONFIG_SOC_1200, CONFIG_SOC_AU1X00, CONFIG_USB_EHCI and
CONFIG_USB_OHCI set.
Furthermore, in ehci-hcd.c, platform_driver_register() was called with
an improper argument of type 'struct device_driver *' which of course
ended up in a kernel oops. How could that ever have worked on your
machines?
Anyway, here's a trivial patch that makes the USB subsystem working
on my board for both OHCI and EHCI.
It also removes the /* FIXME use "struct platform_driver" */.

Subject: [PATCH 331/793] [PATCH] USB: fix visor leaks
This patch fixes blatant leaks in visor driver and makes it report
mode sensible things in ->write_room (this is only needed if your visor
is a terminal though).
It is made to fit into 80 columns with a temporary variable.
Might even save a few instructions...

Subject: [PATCH 332/793] [PATCH] USB: Add some basic WUSB definitions
This patch adds basic Wireless USB 1.0 definitions to usb_ch9.h that
fit into the existing set of declarations. Boils down to two new
recipients for requests (ports and remote pipes), rpipe reset and
abort request codes and wire adapter and remote pipe descriptor
types.
Wire adapters are the USB <-> Wireless USB adaptors; remote pipes
are used by those adapters to pipe the host <-> endpoint traffic.

Universal-2 cable in pl2303
The Susteen Datapilot cable
(http://www.susteen.com/productdetail/71/producthl/Notempty) has an
internal pl2303 to communicate with a set of dummy connector-ends that
connect to a variety of cell phones. I've found that it works right out
of the box by simply adding the product/vendor id to the pl2303 driver.

Subject: [PATCH 335/793] [PATCH] USB: rename Cypress CY7C63xxx driver to
proper name and fix up some tiny things
This is a new driver for the Cypress CY7C63xxx mirco controller series.
It currently supports the pre-programmed CYC63001A-PC by AK Modul-Bus
GmbH. It's based on a kernel 2.4 driver (cyport) by Marcus Maul which I
ported to kernel 2.6 using sysfs. I intend to support more controllers
of this family (and more features) as soon as I get hold of the required
IDs etc. Please see the source code's header for more information.

Subject: [PATCH 337/793] [PATCH] usb-storage: fix race between reset and
disconnect
My recent patch converting usb-storage to use
usb_reset_composite_device() added a bug, a race between reset and
disconnect. It was necessary to drop the private lock while executing a
reset, and if a disconnect occurs at that time it will cause a crash.
This patch (as722) fixes the problem by explicitly checking for an early
termination after executing each command.

Subject: [PATCH 344/793] [PATCH] USB serial visor: fix race in open/close
The anti user-DoS mechanism in the USB serial 'visor' driver can fail in
the following way:
visor_open: priv->outstanding_urbs = 0
visor_write: ++priv->outstanding_urbs
visor_close:
visor_open: priv->outstanding_urbs = 0
visor_write_bulk_callback: --priv->outstanding_urbs
So priv->outstanding_urbs ends up as (unsigned long)(-1). Not good!
I haven't seen this happen with the visor driver as I don't have the
hardware, but I have seen it while testing a patch to implement the same
functionality in the ftdi_sio driver (patch not yet submitted).
The fix is pretty simple: don't reinitialize outstanding_urbs in
visor_open. (Again, I haven't tested the fix in visor, but I have
tested it in ftdi_sio.)

Subject: [PATCH 345/793] [PATCH] USB serial ftdi_sio: Prevent userspace DoS
This patch limits the amount of outstanding 'write' data that can be
queued up for the ftdi_sio driver, to prevent userspace DoS attacks (or
simple accidents) that use up all the system memory by writing lots of
data to the serial port.
The original patch was by Guillaume Autran, who in turn based it on the
same mechanism implemented in the 'visor' driver. I (Ian Abbott)
re-targeted the patch to the latest sources, fixed a couple of errors,
renamed his new structure members, and updated the implementations of
the 'write_room' and 'chars_in_buffer' methods to take account of the
number of outstanding 'write' bytes. It seems to work fine, though at
low baud rates it is still possible to queue up an amount of data that
takes an age to shift (a job for another day!).

Subject: [PATCH 349/793] [PATCH] USB: ehci: fix bogus alteration of a local
variable
In a rare and all-but-unused path, the EHCI driver could reuse a variable
in a way that'd make trouble. Specifically, if the first root hub port
gets an overcurrent event (rare) during a remote wakeup scenario (all but
unused in today's Linux, except for folk working with suspend-to-RAM and
similar sleep states), that would look like a fatal error which would shut
down the controller. Fix by not reusing that variable.

Subject: [PATCH 350/793] [PATCH] USB: ipaq.c bugfixes
This patch fixes several problems in the ipaq.c driver with connecting
and disconnecting pocketpc devices:
* The read urb stayed active if the connect failed, causing nullpointer
dereferences later on.
* If a write failed, the driver continued as if nothing happened. Now it
handles that case the same way as other usb serial devices (fix by
Luiz Fernando N. Capitulino <lcapitulino@mandriva.com.br>)

Subject: [PATCH 351/793] [PATCH] USB: ipaq.c timing parameters
Adds configurable waiting periods to the ipaq connection code. These are
not needed when the pocketpc device is running normally when plugged in,
but they need extra delays if they are physically connected while
rebooting.
There are two parameters :
* initial_wait : this is the delay before the driver attemts to start the
connection. This is needed because the pocktpc device takes much
longer to boot if the driver starts sending control packets too soon.
* connect_retries : this is the number of times the control urb is
retried before finally giving up. The patch also adds a 1 second delay
between retries.
I'm not sure if the cases where this patch is useful are general enough
to include this in the kernel.

Subject: [PATCH 354/793] [PATCH] USB: ipw.c driver fix
The below patch fixes the ipw module in kernel 2.6.17 for me; without
this change it simply does not work at all (all but the first writes are
refused because write_urb_busy is always 1).
This problem was there in 2.6.15 as well, but at that point I used the
(updated) ipw.c, version 0.4, from
http://www.neology.co.za/products/opensource/ipwireless/ which no longer
compiles with 2.6.17. It can be made to after a few changes but
obviously it's easier if the built-in ipw driver works instead of having
to download one from the neology site.

This patch adds the ZyXEL vendor ID to the rtl8150.c driver. The
device has absolutely no identifying marks on the outside for model
type, just a serial number, and I can't find anything on ZyXEL's
website, so I called the product ID PRODUCT_ID_PRESTIGE to match the
product string.

Subject: [PATCH 363/793] [PATCH] USB: gadget section fixups
Recent section changes broke gadget builds on some platforms. This patch
is the best fix that's available until better section markings exist:
- There's a lot of cleanup code that gets used in both init and exit paths;
stop marking it as "__exit".
(Best fix for this would be an "__init_or_exit" section marking, putting
the cleanup in __init when __exit sections get discarded else in __exit.)
- Stop marking the use-once probe routines as "__init" since references
to those routines are not allowed from driver structures. They're now
marked "__devinit", which in practice is a net lose.
(Best fix for this is likely to separate such use-once probe routines
from the driver structure ... but in general, all busses that aren't
hotpluggable will be forced to waste memory for all probe-only code.)
In general these broken section rules waste an average of two to four kBytes
per driver of code bloat ... because none of the relevant code can ever be
reused after module initialization.

USB serial outside of the kernel tree can not build properly due to
usb-serial.h being buried down in the source tree. This patch moves the
location of the file to include/linux/usb and fixes up all of the usb
serial drivers to handle the move properly.

Subject: [PATCH 367/793] [PATCH] PCI: Clear abnormal poweroff flag on VIA
southbridges, fix resume
Some VIA southbridges contain a flag in the ACPI register space that
indicates whether an abnormal poweroff has occured, presumably with the
intention that it can be cleared on clean shutdown. Some BIOSes check this
flag at resume time, and will re-POST the system rather than jump back to
the OS if it's set. Clearing it at boot time appears to be sufficient.
I'm not sure if drivers/pci/quirks.c is the right place to do it, but I'm
not sure where would be cleaner.

Subject: [PATCH 369/793] [PATCH] PCI: PCIE power management quirk
When changing power states from D0->DX and then from DX->D0, some
Intel PCIE chipsets will cause a device reset to occur. This will
cause problems for any D State other than D3, since any state
information that the driver will expect to be present coming from
a D1 or D2 state will have been cleared. This patch addes a
flag to the pci_dev structure to indicate that devices should
not use states D1 or D2, and will set that flag for the affected
chipsets. This patch also modifies pci_set_power_state() so that
when a device driver tries to set the power state on
a device that is downstream from an affected chipset, or on one
of the affected devices it only allows state changes to or
from D0 & D3. In addition, this patch allows the delay time
between D3->D0 to be changed via a quirk. These chipsets also
need additional time to change states beyond the normal 10ms.

Date: Wed, 12 Jul 2006 22:46:42 -0400
Subject: [PATCH 376/793] [PATCH] Revert "ACPI: execute Notify() handlers on
new thread"
This effectively reverts commit b8d35192c55fb055792ff0641408eaaec7c88988
by reverts acpi_os_queue_for_execution() to what it was before that,
except it changes the name to acpi_os_execute() to match ACPICA
20060512.
Signed-off-by: Len Brown <len.brown@intel.com>
[ The thread execution doesn't actually solve the bug it set out to
solve (see
http://bugzilla.kernel.org/show_bug.cgi?id=5534
for more details) because the new events can get caught behind the AML
semaphore or other serialization. And when that happens, the notify
threads keep on piling up until the system dies. ]

Subject: [PATCH 377/793] Revert "[PATCH] pcmcia: Make ide_cs work with the
memory space of CF-Cards if IO space is not available"
This reverts commit 5040cb8b7e61b7a03e8837920b9eb2c839bb1947.
It breaks previously working ide-cs PIO configurations, causing problems
like
ide2: I/O resource 0xF883200E-0xF883200E not free.
ide2: ports already in use, skipping probe
rather than a working kernel.

Subject: [PATCH 381/793] [SPARC64]: Fix 2 bugs in sabre_irq_build()
When installing the IRQ pre-handler, we were not setting up the second
argument correctly. It should be a pointer to the sabre_irq_data, not
the config space PIO address.
Furthermore, we only need this pre-handler installed if the device
sits behind a PCI bridge that is not Sabre or Simba/APB.

Subject: [PATCH 382/793] [SERIAL] sunsu: Handle keyboard and mouse ports
directly.
The sunsu_ports[] array exists merely to be able to easily
use an integer index to get at the proper serial console
port struct.
We size this only for real ports, not for the keyboard and
mouse, and thus keyboard and mouse port registration would
fail.
Fix this by dynamically allocating the port struct for the
keyboard and mouse, instead of using the sunsu_ports[]
array.

Subject: [PATCH 384/793] [SPARC]: Fix OF register translations under sub-PCI
busses.
There is an implicit assumption in the code that ranges will translate
to something that can fit in 2 32-bit cells, or a 64-bit value. For
certain kinds of things below PCI this isn't necessarily true.
Here is what the relevant OF device hierarchy looks like for one of
the serial controllers on an Ultra5:
Node 0xf005f1e0
ranges: 00000000.00000000.00000000.000001fe.01000000.00000000.01000000
01000000.00000000.00000000.000001fe.02000000.00000000.01000000
02000000.00000000.00000000.000001ff.00000000.00000001.00000000
03000000.00000000.00000000.000001ff.00000000.00000001.00000000
device_type: 'pci'
model: 'SUNW,sabre'
Node 0xf005f9d4
device_type: 'pci'
model: 'SUNW,simba'
Node 0xf0060d24
ranges: 00000010.00000000 82010810.00000000.f0000000 01000000
00000014.00000000 82010814.00000000.f1000000 00800000
name: 'ebus'
Node 0xf0062dac
reg: 00000014.003083f8.00000008 --> 0x1ff.f13083f8
device_type: 'serial'
name: 'su'
So the correct translation here is:
1) Match "su" register to second ranges entry of 'ebus', which translates
into a PCI triplet "82010814.00000000.f1000000" of size 00800000, which
gives us "82010814.00000000.f13083f8".
2) Pass-through "SUNW,simba" since it lacks ranges property
3) Match "82010814.00000000.f13083f8" to third ranges property of PCI
controller node 'SUNW,sabre', and we arrive at the final physical
MMIO address of "0x1fff13083f8".
Due to the 2-cell assumption, we couldn't translate to a PCI 3-cell
value, and we couldn't perform a pass-thru on it either.
It was easiest to just stop splitting the ranges application operation
between two methods, ->map and ->translate, and just let ->map do all
the work. That way it would work purely on 32-bit cell arrays instead
of having to "return" some value like a u64.
It's still not %100 correct because the out-of-range check is still
done using the 64 least significant bits of the range and address.
But it does work for all the cases I've thrown at it so far.

Subject: [PATCH 394/793] [PATCH] i386: system.h: remove extra semicolons and
fix order
include/asm-i386/system.h has trailing semicolons in some of the
macros that cause legitimate code to fail compilation, so remove
them. Also remove extra blank lines within one group of macros.
And put stts() and clts() back together; they got separated somehow.

macro
Keep the result holder variable the same type as the quantity we are
retreiving in the get_user() macro - don't go through a pointer version
of the user space address type.
Using the address type causes problems if the address type was const
(newer versions of gcc quite rightly error out for that condition).

O2 Micro's controllers have a larger specification version value and are
therefore denied by the driver. When bypassing this check they seem to work

Subject: [PATCH 400/793] [PATCH] lockdep: annotate mm/slab.c
mm/slab.c uses nested locking when dealing with 'off-slab'
caches, in that case it allocates the slab header from the
(on-slab) kmalloc caches. Teach the lock validator about
this by putting all on-slab caches into a separate class.
this patch has no effect on non-lockdep kernels.

build
As a result of 894673ee6122a3ce1958e1fe096901ba5356a96b, the ARM
architecture is more or less unbuildable - only one defconfig appears
to build, with all others erroring out with:
CC arch/arm/kernel/setup.o
In file included from /home/rmk/git/linux-2.6-rmk/arch/arm/kernel/setup.c:22:
/home/rmk/git/linux-2.6-rmk/include/linux/root_dev.h:7: warning: implicit declaration of function `MKDEV'
...
Essentially, root_dev.h uses MKDEV and dev_t, but does not include any
headers which provide either of these definitions. The reason it worked
previously is that linux/tty.h just happened to include the required
headers for linux/root_dev.h.

Subject: [PATCH 422/793] [MIPS] Sibyte: Improve interrupt latency again for
sb1250/bcm1480
this patch restores the behaviour of the old (assembly-written)
interrupt handler, the handler is left as soon as a single interrupt
cause is handled.

Subject: [PATCH 428/793] [MIPS] Do not count pages in holes with sparsemem
With some memory model other than FLATMEM, the single node can
contains some holes so there might be many invalid pages. For
example, with two 256M memory and one 256M hole, some variables
(num_physpage, totalpages, nr_kernel_pages, nr_all_pages, etc.) will
indicate that there are 768MB on this system. This is not desired
because, for example, alloc_large_system_hash() allocates too many
entries.
Use free_area_init_node() with counted zholes_size[] instead of
free_area_init().
For num_physpages, use number of ram pages instead of max_low_pfn.

- *
- * 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in

- * Furthermore, the IRQs on the MIPS board look basically (barring software

- * 3 Hardware (ignored)
- * 4 Hardware (ignored)
- * 5 Hardware (ignored)
- * 6 Hardware (ignored)
- * 7 R4k timer (what we use)
- *
- * Note: On the SEAD board thing are a little bit different.
- * Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
- * wired to UART1.
- *
- * We handle the IRQ according to _our_ priority which is:
- *
- * Highest ---- R4k Timer
- * Lowest ---- Combined hardware interrupt
- *
- * then we just return, if multiple IRQs are pending then we will just take

Chandra Seetharaman reported SLAB crashes caused by the slab.c lock
annotation patch. There is only one chunk of that patch that has a
material effect on the slab logic - this patch undoes that chunk.
This was confirmed to fix the slab problem by Chandra.

Subject: [PATCH 456/793] [NET]: Update frag_list in pskb_trim
When pskb_trim has to defer to ___pksb_trim to trim the frag_list part of
the packet, the frag_list is not updated to reflect the trimming. This
will usually work fine until you hit something that uses the packet length
or tail from the frag_list.
Examples include esp_output and ip_fragment.
Another problem caused by this is that you can end up with a linear packet
with a frag_list attached.
It is possible to get away with this if we audit everything to make sure
that they always consult skb->len before going down onto frag_list. In
fact we can do the samething for the paged part as well to avoid copying
the data area of the skb. For now though, let's do the conservative fix
and update frag_list.
Many thanks to Marco Berizzi for helping me to track down this bug.
This 4-year old bug took 3 months to track down. Marco was very patient
indeed :)

So the field needs to be cleared before it confuses the route code.
This was seen when running netem over loopback, but there are probably
other device cases. Maybe this should go into stable?

The original suggested fix for netpoll was found to be racy on SMP
kernels. While it is highly unlikely that this race would ever be seen
in the real world due to current netpoll usage models, we implemented
this updated fix to address concerns.

A panic was reported when receiving 1522 size packets if using

value that e1000changemtu sets so that we can receive any packet
that would not be dropped by LPE=0.

2.6.16 leaks like hell. While testing, I found massive leakage
(reproduced in openvz) in:
*filp

And 1 object leaks in
*size-32
*size-64
*size-128
It is the fix for the first one. filp leaks in the bowels of namei.c.
Seems, size-4096 is file table leaking in expand_fdtables.
I have no idea what are the rest and why they show only accompanying
another leaks. Some debugging structs?

Subject: [PATCH 476/793] [PATCH] IB/mthca: comment fix
After recent changes, mthca_wq_init does not actually initialize the WQ as it
used to - it simply resets all index fields to their initial values. So,
let's rename it to mthca_wq_reset.

Subject: [PATCH 477/793] [PATCH] IB/cm: drop REQ when out of memory
If a user of the IB CM returns -ENOMEM from their connection callback, simply
drop the incoming REQ - do not attempt to send a reject. This should allow
the sender to retry the request.

ib_fmr_pool_map_phys gets the virtual address by pointer but never writes
there, and users (e.g. srp) seem to assume this and ignore the value
returned. This patch cleans up the API to get the VA by value, and updates
all users.

Subject: [PATCH 483/793] [PATCH] mm: fix oom roll-back of __vmalloc_area_node
__vunmap must not rely on area->nr_pages when picking the release methode
for area->pages. It may be too small when __vmalloc_area_node failed early
due to lacking memory. Instead, use a flag in vmstruct to differentiate.

Subject: [PATCH 484/793] [PATCH] ia64: race flushing icache in COW path
There is a race condition that showed up in a threaded JIT environment.
The situation is that a process with a JIT code page forks, so the page is
marked read-only, then some threads are created in the child. One of the
threads attempts to add a new code block to the JIT page, so a
copy-on-write fault is taken, and the kernel allocates a new page, copies
the data, installs the new pte, and then calls lazy_mmu_prot_update() to
flush caches to make sure that the icache and dcache are in sync.
Unfortunately, the other thread runs right after the new pte is installed,
but before the caches have been flushed. It tries to execute some old JIT
code that was already in this page, but it sees some garbage in the i-cache
from the previous users of the new physical page.
Fix: we must make the caches consistent before installing the pte. This is
an ia64 only fix because lazy_mmu_prot_update() is a no-op on all other
architectures.

Subject: [PATCH 487/793] [PATCH] i386 kexec: allow the kexec on panic support
to compile on voyager
This patch removes the foolish assumption that SMP implied local apics.
That assumption is not-true on the Voyager subarch. This makes that
dependency explicit, and allows the code to build.
What gets disabled is just an optimization to get better crash dumps so the
support should work if there is a kernel that will initialization on the
voyager subarch under those harsh conditions.
Hopefully we can figure out how to initialize apics in init_IRQ and remove
the need to disable io_apics and this dependency.

Subject: [PATCH 488/793] [PATCH] i386: remove redundant might_sleep() in user
accessors.
On i386, the user space accessor functions copy_from/to_user() both invoke
might_sleep(), do a quick sanity check, and then pass the work on to their
__copy_from/to_user() counterparts, which again invoke might_sleep().
Given that no actual work happens between these two calls, it is best to
eliminate one of the redundant might_sleep()s.

Subject: [PATCH 492/793] [PATCH] null-terminate over-long /proc/kallsyms
symbols
Got a customer bug report (https://bugzilla.novell.com/190296) about kernel
symbols longer than 127 characters which end up in a string buffer that is
not NULL terminated, leading to garbage in /proc/kallsyms. Using strlcpy
prevents this from happening, even though such symbols still won't come out
right.
A better fix would be to not use a fixed-size buffer, but it's probably not
worth the trouble. (Modversion'ed symbols even have a length limit of 60.)

This isn't suitable for userspace to see -- the kernel headers are not a
random library of stuff for userspace; they're only there to define the
kernel<->user ABI for system libraries and tools. Anything which _was_
abusing asm/atomic.h from userspace was probably broken anyway -- as it often
didn't even give atomic operation.

There's no excuse for userspace abusing this kernel header -- the kernel's
headers are not intended to provide a library of helper routines for
userspace. Using <asm/io.h> from userspace is broken on most architectures
anyway. Just say 'no'.

Subject: [PATCH 500/793] [PATCH] ramdisk blocksize Kconfig entry
Make the ramdisk blocksize configurable at kernel compilation time rather
than only at boot or module load time, like a couple of the other ramdisk
options. I found this handy awhile back but thought little of it, until
recently asked by a few of the testing folks here to be able to do the same
thing for their automated test setups.
The Kconfig comment is largely lifted from comments in rd.c, and hopefully
this will increase the chances of making folks aware that the default value
often isn't a great choice here (for increasing values of PAGE_SIZE, even
moreso).

The delete partition IOCTL takes the bd_mutex for both the disk and the

Subject: [PATCH 503/793] [PATCH] Add try_to_freeze() to rt-test kthreads
When CONFIG_RT_MUTEX_TESTER is enabled kernel refuses to suspend the
machine because it's unable to freeze the rt-test-* threads.
Add try_to_freeze() after schedule() so that the threads will be freezed
correctly; I've tested the patch and it lets the notebook suspends and
resumes nicely.

Christoph Hellwig:
open_softirq just enables a softirq. The softirq array is statically
allocated so to add a new one you would have to patch the kernel. So
there's no point to keep this export at all as any user would have to
patch the enum in include/linux/interrupt.h anyway.

Subject: [PATCH 506/793] [PATCH] scx200_gpio: 1 cdev for N minors: cleanup,
prep
this patch is mostly cleanup of scx200_gpio :
- drop #include <linux/config.h>
- s/DEVNAME/DRVNAME/ apparently a convention
- replace variable num_pins with #define MAX_PINS
- s/dev/devid/ to clarify that its a dev_t, not a struct device dev.
- move devid = MKDEV(major,0) into branch where its needed.
2 minor 'changes' :
- reduced MAX_PINS from 64 to 32. Ive never tested other pins, and
theyre all multiplexed with other functions, some of which may be in use
on my soekris 4801, so I dont know what testing should yield.
- +EXPORT_SYMBOL(scx200_access);
This exposes the driver's vtable, which another driver can use along
with #include <linux/nsc_gpio.h>, to manipulate a gpio-pin.

for N
Remove the scx200_gpio's cdev-array & ksalloc, replacing it with a single
static struct cdev, which is sufficient for all the pins.
cdev_put is commented out since kernel wont link properly with it, and its
apparently not needed.
With these patches, this driver continues to work with Chris Boot's
leds_48xx driver.

Subject: [PATCH 511/793] [PATCH] reiserfs: fix handling of device names with
/'s in them
On systems with block devices containing a slash (virtual dasd, cciss,
etc), reiserfs will fail to initialize /proc/fs/reiserfs/<dev> due to it
being interpreted as a subdirectory. The generic block device code changes
the / to ! for use in the sysfs tree. This patch uses that convention.
Tested by making dm devices use dm/<number> rather than dm-<number>
[akpm@osdl.org: name variables consistently]

Subject: [PATCH 512/793] [PATCH] Convert idr's internal locking to _irqsave
variant
Currently, the code in lib/idr.c uses a bare spin_lock(&idp->lock) to do
internal locking. This is a nasty trap for code that might call idr
functions from different contexts; for example, it seems perfectly
reasonable to call idr_get_new() from process context and idr_remove() from
interrupt context -- but with the current locking this would lead to a
potential deadlock.
The simplest fix for this is to just convert the idr locking to use
spin_lock_irqsave().
In particular, this fixes a very complicated locking issue detected by
lockdep, involving the ib_ipoib driver's priv->lock and dev->_xmit_lock,
which get involved with the ib_sa module's query_idr.lock.

Subject: [PATCH 518/793] [PATCH] lockdep: core, fix rq-lock handling on
__ARCH_WANT_UNLOCKED_CTXSW
On platforms that have __ARCH_WANT_UNLOCKED_CTXSW set and want to implement
lock validator support there's a bug in rq->lock handling: in this case we
dont 'carry over' the runqueue lock into another task - but still we did a
spinlock_release() of it. Fix this by making the spinlock_release() in
context_switch() dependent on !__ARCH_WANT_UNLOCKED_CTXSW.
(Reported by Ralf Baechle on MIPS, which has __ARCH_WANT_UNLOCKED_CTXSW.
This fixes a lockdep-internal BUG message on such platforms.)

Subject: [PATCH 526/793] [PATCH] Fix security check for joint context= and
fscontext= mount options
After some discussion on the actual meaning of the filesystem class
security check in try context mount it was determined that the checks for
the context= mount options were not correct if fscontext mount option had
already been used.
When labeling the superblock we should be checking relabel_from and
relabel_to. But if the superblock has already been labeled (with
fscontext) then context= is actually labeling the inodes, and so we should
be checking relabel_from and associate. This patch fixes which checks are
called depending on the mount options.

Subject: [PATCH 529/793] [PATCH] per-task-delay-accounting: setup
Initialization code related to collection of per-task "delay" statistics which
measure how long it had to wait for cpu, sync block io, swapping etc. The
collection of statistics and the interface are in other patches. This patch
sets up the data structures and allows the statistics collection to be
disabled through a kernel boot parameter.

Subject: [PATCH 530/793] [PATCH] per-task-delay-accounting: sync block I/O and
swapin delay collection
Unlike earlier iterations of the delay accounting patches, now delays are only
collected for the actual I/O waits rather than try and cover the delays seen
in I/O submission paths.
Account separately for block I/O delays incurred as a result of swapin page
faults whose frequency can be affected by the task/process' rss limit. Hence
swapin delays can act as feedback for rss limit changes independent of I/O
priority changes.

Subject: [PATCH 531/793] [PATCH] per-task-delay-accounting: cpu delay
collection via schedstats
Make the task-related schedstats functions callable by delay accounting even
if schedstats collection isn't turned on. This removes the dependency of
delay accounting on schedstats.

Subject: [PATCH 533/793] [PATCH] per-task-delay-accounting: taskstats
interface
Create a "taskstats" interface based on generic netlink (NETLINK_GENERIC
family), for getting statistics of tasks and thread groups during their
lifetime and when they exit. The interface is intended for use by multiple
accounting packages though it is being created in the context of delay
accounting.
This patch creates the interface without populating the fields of the data
that is sent to the user in response to a command or upon the exit of a task.
Each accounting package interested in using taskstats has to provide an
additional patch to add its stats to the common structure.

+Per-task statistics interface
+-----------------------------
+
+
+Taskstats is a netlink-based interface for sending per-task and
+per-process statistics from the kernel to userspace.
+
+Taskstats was designed for the following benefits:
+
+- efficiently provide statistics during lifetime of a task and on its exit
+- unified interface for multiple accounting subsystems
+- extensibility for use by future accounting patches
+
+Terminology
+-----------
+
+"pid", "tid" and "task" are used interchangeably and refer to the standard
+Linux task defined by struct task_struct. per-pid stats are the same as
+per-task stats.
+
+"tgid", "process" and "thread group" are used interchangeably and refer to the
+tasks that share an mm_struct i.e. the traditional Unix process. Despite the
+use of tgid, there is no special treatment for the task that is thread group
+leader - a process is deemed alive as long as it has any task belonging to it.
+
+Usage
+-----
+
+To get statistics during task's lifetime, userspace opens a unicast netlink
+socket (NETLINK_GENERIC family) and sends commands specifying a pid or a tgid.
+The response contains statistics for a task (if pid is specified) or the sum of
+statistics for all tasks of the process (if tgid is specified).
+
+To obtain statistics for tasks which are exiting, userspace opens a multicast
+netlink socket. Each time a task exits, two records are sent by the kernel to
+each listener on the multicast socket. The first the per-pid task's statistics
+and the second is the sum for all tasks of the process to which the task
+belongs (the task does not need to be the thread group leader). The need for
+per-tgid stats to be sent for each exiting task is explained in the per-tgid
+stats section below.
+
+
+Interface
+---------
+
+The user-kernel interface is encapsulated in include/linux/taskstats.h
+
+To avoid this documentation becoming obsolete as the interface evolves, only
+an outline of the current version is given. taskstats.h always overrides the
+description here.
+
+struct taskstats is the common accounting structure for both per-pid and
+per-tgid data. It is versioned and can be extended by each accounting subsystem
+that is added to the kernel. The fields and their semantics are defined in the
+taskstats.h file.
+
+The data exchanged between user and kernel space is a netlink message belonging
+to the NETLINK_GENERIC family and using the netlink attributes interface.
+The messages are in the format
+
+ +----------+- - -+-------------+-------------------+
+ | nlmsghdr | Pad | genlmsghdr | taskstats payload |
+ +----------+- - -+-------------+-------------------+
+
+
+The taskstats payload is one of the following three kinds:
+
+1. Commands: Sent from user to kernel. The payload is one attribute, of type
+TASKSTATS_CMD_ATTR_PID/TGID, containing a u32 pid or tgid in the attribute
+payload. The pid/tgid denotes the task/process for which userspace wants
+statistics.
+
+2. Response for a command: sent from the kernel in response to a userspace
+command. The payload is a series of three attributes of type:
+
+a) TASKSTATS_TYPE_AGGR_PID/TGID : attribute containing no payload but indicates
+a pid/tgid will be followed by some stats.
+
+b) TASKSTATS_TYPE_PID/TGID: attribute whose payload is the pid/tgid whose stats
+is being returned.
+
+c) TASKSTATS_TYPE_STATS: attribute with a struct taskstsats as payload. The
+same structure is used for both per-pid and per-tgid stats.
+
+3. New message sent by kernel whenever a task exits. The payload consists of a
+ series of attributes of the following type:
+
+a) TASKSTATS_TYPE_AGGR_PID: indicates next two attributes will be pid+stats
+b) TASKSTATS_TYPE_PID: contains exiting task's pid
+c) TASKSTATS_TYPE_STATS: contains the exiting task's per-pid stats
+d) TASKSTATS_TYPE_AGGR_TGID: indicates next two attributes will be tgid+stats
+e) TASKSTATS_TYPE_TGID: contains tgid of process to which task belongs
+f) TASKSTATS_TYPE_STATS: contains the per-tgid stats for exiting task's process
+
+
+per-tgid stats
+--------------
+
+Taskstats provides per-process stats, in addition to per-task stats, since
+resource management is often done at a process granularity and aggregating task
+stats in userspace alone is inefficient and potentially inaccurate (due to lack
+of atomicity).
+
+However, maintaining per-process, in addition to per-task stats, within the
+kernel has space and time overheads. Hence the taskstats implementation
+dynamically sums up the per-task stats for each task belonging to a process
+whenever per-process stats are needed.
+
+Not maintaining per-tgid stats creates a problem when userspace is interested
+in getting these stats when the process dies i.e. the last thread of
+a process exits. It isn't possible to simply return some aggregated per-process
+statistic from the kernel.
+
+The approach taken by taskstats is to return the per-tgid stats *each* time
+a task exits, in addition to the per-pid stats for that task. Userspace can
+maintain task<->process mappings and use them to maintain the per-process stats
+in userspace, updating the aggregate appropriately as the tasks of a process
+exit.
+
+Extending taskstats
+-------------------
+
+There are two ways to extend the taskstats interface to export more
+per-task/process stats as patches to collect them get added to the kernel
+in future:
+
+1. Adding more fields to the end of the existing struct taskstats. Backward
+ compatibility is ensured by the version number within the
+ structure. Userspace will use only the fields of the struct that correspond
+ to the version its using.
+
+2. Defining separate statistic structs and using the netlink attributes
+ interface to return them. Since userspace processes each netlink attribute
+ independently, it can always ignore attributes whose type it does not
+ understand (because it is using an older version of the interface).
+
+
+Choosing between 1. and 2. is a matter of trading off flexibility and
+overhead. If only a few fields need to be added, then 1. is the preferable
+path since the kernel and userspace don't need to incur the overhead of
+processing new netlink attributes. But if the new fields expand the existing
+struct too much, requiring disparate userspace accounting utilities to
+unnecessarily receive large structures whose fields are of no interest, then
+extending the attributes structure would be worthwhile.

+Delay accounting
+----------------
+
+Tasks encounter delays in execution when they wait
+for some kernel resource to become available e.g. a
+runnable task may wait for a free CPU to run on.
+
+The per-task delay accounting functionality measures
+the delays experienced by a task while
+
+a) waiting for a CPU (while being runnable)
+b) completion of synchronous block I/O initiated by the task
+c) swapping in pages
+
+and makes these statistics available to userspace through
+the taskstats interface.
+
+Such delays provide feedback for setting a task's cpu priority,
+io priority and rss limit values appropriately. Long delays for
+important tasks could be a trigger for raising its corresponding priority.
+
+The functionality, through its use of the taskstats interface, also provides
+delay statistics aggregated for all tasks (or threads) belonging to a
+thread group (corresponding to a traditional Unix process). This is a commonly
+needed aggregation that is more efficiently done by the kernel.
+
+Userspace utilities, particularly resource management applications, can also
+aggregate delay statistics into arbitrary groups. To enable this, delay
+statistics of a task are available both during its lifetime as well as on its
+exit, ensuring continuous and complete monitoring can be done.
+
+
+Interface
+---------
+
+Delay accounting uses the taskstats interface which is described
+in detail in a separate document in this directory. Taskstats returns a
+generic data structure to userspace corresponding to per-pid and per-tgid
+statistics. The delay accounting functionality populates specific fields of
+this structure. See
+ include/linux/taskstats.h
+for a description of the fields pertaining to delay accounting.
+It will generally be in the form of counters returning the cumulative
+delay seen for cpu, sync block I/O, swapin etc.
+
+Taking the difference of two successive readings of a given
+counter (say cpu_delay_total) for a task will give the delay
+experienced by the task waiting for the corresponding resource
+in that interval.
+
+When a task exits, records containing the per-task and per-process statistics
+are sent to userspace without requiring a command. More details are given in
+the taskstats interface description.
+
+The getdelays.c userspace utility in this directory allows simple commands to
+be run and the corresponding delay statistics to be displayed. It also serves
+as an example of using the taskstats interface.
+
+Usage
+-----
+
+Compile the kernel with
+ CONFIG_TASK_DELAY_ACCT=y
+ CONFIG_TASKSTATS=y
+
+Enable the accounting at boot time by adding
+the following to the kernel boot options
+ delayacct
+
+and after the system has booted up, use a utility
+similar to getdelays.c to access the delays
+seen by a given task or a task group (tgid).
+The utility also allows a given command to be
+executed and the corresponding delays to be
+seen.
+
+General format of the getdelays command
+
+getdelays [-t tgid] [-p pid] [-c cmd...]
+
+
+Get delays, since system boot, for pid 10
+# ./getdelays -p 10
+(output similar to next case)
+
+Get sum of delays, since system boot, for all pids with tgid 5
+# ./getdelays -t 5
+
+
+CPU count real total virtual total delay total
+ 7876 92005750 100000000 24001500
+IO count delay total
+ 0 0
+MEM count delay total
+ 0 0
+
+Get delays seen in executing a given simple command
+# ./getdelays -c ls /
+
+bin data1 data3 data5 dev home media opt root srv sys usr
+boot data2 data4 data6 etc lib mnt proc sbin subdomain tmp var

Send per-tgid data only once during exit of a thread group instead of once
with each member thread exit.
Currently, when a thread exits, besides its per-tid data, the per-tgid data
of its thread group is also sent out, if its thread group is non-empty.
The per-tgid data sent consists of the sum of per-tid stats for all
*remaining* threads of the thread group.
This patch modifies this sending in two ways:
- the per-tgid data is sent only when the last thread of a thread group
exits. This cuts down heavily on the overhead of sending/receiving
per-tgid data, especially when other exploiters of the taskstats
interface aren't interested in per-tgid stats
- the semantics of the per-tgid data sent are changed. Instead of being
the sum of per-tid data for remaining threads, the value now sent is the
true total accumalated statistics for all threads that are/were part of
the thread group.
The patch also addresses a minor issue where failure of one accounting
subsystem to fill in the taskstats structure was causing the send of
taskstats to not be sent at all.
The patch has been tested for stability and run cerberus for over 4 hours
on an SMP.

Subject: [PATCH 539/793] [PATCH] per-task delay accounting: avoid send without
listeners
Don't send taskstats (per-pid or per-tgid) on thread exit when no one is
listening for such data.
Currently the taskstats interface allocates a structure, fills it in and
calls netlink to send out per-pid and per-tgid stats regardless of whether
a userspace listener for the data exists (netlink layer would check for
that and avoid the multicast).
As a result of this patch, the check for the no-listener case is performed
early, avoiding the redundant allocation and filling up of the taskstats
structures.

Subject: [PATCH 540/793] [PATCH] per-task delay accounting taskstats
interface: control exit data through cpumasks
On systems with a large number of cpus, with even a modest rate of tasks
exiting per cpu, the volume of taskstats data sent on thread exit can
overflow a userspace listener's buffers.
One approach to avoiding overflow is to allow listeners to get data for a
limited and specific set of cpus. By scaling the number of listeners
and/or the cpus they monitor, userspace can handle the statistical data
overload more gracefully.
In this patch, each listener registers to listen to a specific set of cpus
by specifying a cpumask. The interest is recorded per-cpu. When a task
exits on a cpu, its taskstats data is unicast to each listener interested
in that cpu.
Thanks to Andrew Morton for pointing out the various scalability and
general concerns of previous attempts and for suggesting this design.

Subject: [PATCH 541/793] [PATCH] Remove down_write() from taskstats code
invoked on the exit() path
In send_cpu_listeners(), which is called on the exit path, a down_write()
was protecting operations like skb_clone() and genlmsg_unicast() that do
GFP_KERNEL allocations. If the oom-killer decides to kill tasks to satisfy
the allocations,the exit of those tasks could block on the same semphore.
The down_write() was only needed to allow removal of invalid listeners from
the listener list. The patch converts the down_write to a down_read and
defers the removal to a separate critical region. This ensures that even
if the oom-killer is called, no other task's exit is blocked as it can
still acquire another down_read.
Thanks to Andrew Morton & Herbert Xu for pointing out the oom related
pitfalls, and to Chandra Seetharaman for suggesting this fix instead of
using something more complex like RCU.

Subject: [PATCH 543/793] [PATCH] remove set_wmb - arch removal
set_wmb should not be used in the kernel because it just confuses the
code more and has no benefit. Since it is not currently used in the
kernel this patch removes it so that new code does not include it.
All archs define set_wmb(var, value) to do { var = value; wmb(); }
while(0) except ia64 and sparc which use a mb() instead. But this is
still moot since it is not used anyway.
Hasn't been tested on any archs but x86 and x86_64 (and only compiled
tested)

Subject: [PATCH 546/793] Don't allow chmod() on the /proc/<pid>/ files
This just turns off chmod() on the /proc/<pid>/ files, since there is no
good reason to allow it, and had we disallowed it originally, the nasty
/proc race exploit wouldn't have been possible.
The other patches already fixed the problem chmod() could cause, so this
is really just some final mop-up..
This particular version is based off a patch by Eugene and Marcel which
had much better naming than my original equivalent one.

Subject: [PATCH 548/793] [PATCH] UML - fix utsname build breakage
Some -mm-only material leaked into a patch destined for mainline, and I didn't
notice.
This was the replacement of system_utsname with utsname() that's required by
the uts namespace patch. This patch reverts those changes (which are correct
in -mm) so that mainline UML builds again.

Subject: [PATCH 550/793] [PATCH] ata_piix: add host_set private structure
Add host_set private structure piix_host_priv. Currently the only
field is ->map which used to be stored directly at
host_set->private_data. This change allows more host_set private
fields to be added.

Subject: [PATCH 551/793] [libata] ata_piix: Consolidate PCS register writing
Prior to this patch, the driver would do this for each port:
read 8-bit PCS
write 8-bit PCS
read 8-bit PCS
write 8-bit PCS
In the field, flaky behavior has been observed related to this register.
In particular, these overzealous register writes can cause misdetection
problems.
Update to do the following once (not once per port) at boot:
read 16-bit PCS
if needs changing,
write 16-bit PCS
And thereafter, we only perform a 'read 16-bit PCS' per port.
This should eliminate all PCS writes in many cases, and be more friendly
in the cases where we do need to enable ports.

When sky2 driver gets lots of received packets at once, it can get stuck.
The NAPI poll routine gets called back to keep going, but since no IRQ bits

Increase version, since this is serious enough problem that I want to be
able to tell new from old problems.

With this patch TX queue descriptors are not chained per default any more.
The pointer to next descriptor is set only when next descriptor is prepaired
for transfer. Also the mechanism of checking wether Spider is ready has been
changed: it checks not for CARDOWNED flag in status of previous descriptor
but for a TXDMAENABLED flag in Spider's register.

Subject: [PATCH 565/793] [PATCH] libata: fix autopsy ehc->i.action and
ehc->i.dev handling
Commit 0662c58b3265f52f708a6d59476bc7862b01f9c0 updated
ata_eh_autopsy() to OR determined action to ehc->i.action to preserve
action mask set directly into ehc->i.action by nested functions. This
broke action mask clearing on SENSE_VALID case causing revalidation
and EH complete message on successful ATAPI CC.
This patch removes two local variables - action and failed_dev - which
cache ehc->i.action and ehc->i.dev respectively, and make the function
directly modify ehc->i.* fields to remove aliasing issues.

Subject: [PATCH 566/793] [PATCH] libata: fix eh_skip_recovery condition
* (ata_dev_absent() || ata_dev_ready()) test doesn't indicate
SUSPENDED state properly. Fix it.
* Link resuming resets shouldn't be skipped. Don't skip recovery on
EHI_RESUME_LINK. This doesn't matter for host ports as EHI_RESUME
always coincides with EHI_HOTPLUGGED which makes attached disabled
devices vacant. However, PMP reset causes non-hotplug link-resuming
resets which shouldn't be skipped.

Subject: [PATCH 567/793] [PATCH] libata: improve EH action and EHI flag
handling
Update ata_eh_about_to_do() and ata_eh_done() to improve EH action and
EHI flag handling.
* There are two types of EHI flags - one which expires on successful
EH and the other which expires on a successful reset. Make this
distinction clear.
* Unlike other EH actions, reset actions are represented by two EH
action masks and a EHI modifier. Implement correct about_to_do/done
semantics for resets. That is, prior to reset, related EH info is
sucked in from ehi and cleared, and after reset is complete, related
EH info in ehc is cleared.
These changes improve consistency and remove unnecessary EH actions
caused by stale EH action masks and EHI flags.

Subject: [PATCH 569/793] [SPARC64]: Fix more of_device layer IRQ bugs, and
correct PROMREG_MAX.
Sabre and Psycho PCI controllers can have partial interrupt-map
properties, meaning that on-board devices don't match up to any
entries. Instead, they are fully specified from the beginning and
we should pass them directly to the IRQ translator as-is.
Also, fill in the necessary translator slots for the "graphics"
and "expansion UPA" interrupts on Sabre, Psycho, and SYSIO SBUS.
Increase PROMREG_MAX to 24, as seen on SUNW,ffb devices.
Finally, prevent accidentally writing past the end of the of_device
struct resource[] and irqs[] arrays. Spit out a log message when
we ignore some entries because there are too many of them.

Subject: [PATCH 582/793] [SERIAL] sunzilog: Fix instance enumeration.
Just do a linear enumeration so that we handle sun4d systems
correctly. As a consequence, eliminate the hard coded keyboard and
mouse channel line values, use the CONS_{KEYB,MS} flags instead.
Also, report the keyboard/mouse Zilog channels just like the uart ones
do.

Subject: [PATCH 585/793] [IPV4]: Get rid of redundant IPCB->opts
initialisation
Now that we always zero the IPCB->opts in ip_rcv, it is no longer
necessary to do so before calling netif_rx for tunneled packets.

Date: Fri, 21 Jul 2006 14:45:25 -0700
Subject: [PATCH 589/793] [PKT_SCHED] netem: Fix slab corruption with netem
(2nd try)
CONFIG_DEBUG_SLAB found the following bug:
netem_enqueue() in sch_netem.c gets a pointer inside a slab object:
struct netem_skb_cb *cb = (struct netem_skb_cb *)skb->cb;
But then, the slab object may be freed:
skb = skb_unshare(skb, GFP_ATOMIC)
cb is still pointing inside the freed skb, so here is a patch to
initialize cb later, and make it clear that initializing it sooner
is a bad idea.
[From Stephen Hemminger: leave cb unitialized in order to let gcc
complain in case of use before initialization]

Subject: [PATCH 593/793] [SCTP]: Set chunk->data_accepted only if we are going
to accept it.
Currently there is a code path in sctp_eat_data() where it is possible
to set this flag even when we are dropping this chunk.

Subject: [PATCH 595/793] [I/OAT]: net/core/user_dma.c should #include
<net/netdma.h>
Every file should #include the headers containing the prototypes for
its global functions.
Especially in cases like this one where gcc can tell us through a
compile error that the prototype was wrong...

Subject: [PATCH 597/793] [IrDA]: Use alloc_skb() in IrDA TX path
As pointed out by Christoph Hellwig, dev_alloc_skb() is not intended to be
used for allocating TX sk_buff. The IrDA stack was exclusively calling
dev_alloc_skb() on the TX path, and this patch fixes that.

Subject: [PATCH 604/793] [IPV4]: Fix nexthop realm dumping for multipath
routes
Routing realms exist per nexthop, but are only returned to userspace
for the first nexthop. This is due to the fact that iproute2 only
allows to set the realm for the first nexthop and the kernel refuses
multipath routes where only a single realm is present.
Dump all realms for multipath routes to enable iproute to correctly
display them.

and infinite wait for the workqueue to shut down).

Subject: [PATCH 607/793] cpu hotplug: simplify and hopefully fix locking
The CPU hotplug locking was quite messy, with a recursive lock to
handle the fact that both the actual up/down sequence wanted to
protect itself from being re-entered, but the callbacks that it
called also tended to want to protect themselves from CPU events.
This splits the lock into two (one to serialize the whole hotplug
sequence, the other to protect against the CPU present bitmaps
changing). The latter still allows recursive usage because some
subsystems (ondemand policy for cpufreq at least) had already gotten
too used to the lax locking, but the locking mistakes are hopefully
now less fundamental, and we now warn about recursive lock usage
when we see it, in the hope that it can be fixed.

Subject: [PATCH 608/793] [PATCH] Cpuset: fix ABBA deadlock with cpu hotplug
lock
Fix ABBA deadlock between lock_cpu_hotplug() and the cpuset
callback_mutex lock.
It only happens on cpu_exclusive cpusets, due to the dynamic
sched domain code trying to take the cpu hotplug lock inside
the cpuset callback_mutex lock.
This bug has apparently been here for several months, but didn't
get hit until the right customer load on a large system.
This fix appears right from inspection, but it will take a few
more days running it on that customers workload to be confident
we nailed it. We don't have any other reproducible test case.
The cpu_hotplug_lock() tends to cover large runs of code.
The other places that hold both that lock and the cpuset callback
mutex lock always nest the cpuset lock inside the hotplug lock.
This place tries to do the reverse, risking an ABBA deadlock.
This is in the cpuset_rmdir() code, where we:
* take the callback_mutex lock
* mark the cpuset CS_REMOVED
* call update_cpu_domains for cpu_exclusive cpusets
* in that call, take the cpu_hotplug lock if the
cpuset is marked for removal.
Thanks to Jack Steiner for identifying this deadlock.
The fix is to tear down the dynamic sched domain before we grab
the cpuset callback_mutex lock. This way, the two locks are
serialized, with the hotplug lock taken and released before
trying for the cpuset lock.
I suspect that this bug was introduced when I changed the
cpuset locking from one lock to two. The dynamic sched domain
dependency on cpu_exclusive cpusets and its hotplug hooks were
added to this code earlier, when cpusets had only a single lock.
It may well have been fine then.

Subject: [PATCH 614/793] IB/ipath: Fix ib_ipath driver to work with SRP
I am still working on a proposal to remove the phys_to_virt() calls
in the ib_ipath driver. In the mean time, this patch allows SRP
to work by fixing the R_Key check and conversion from IB address
to kernel virtual address. It also returns the correct page size
for FMRs.

Subject: [PATCH 615/793] IB/ipath: ipath_skip_sge() can break if num_sge > 1
ipath_skip_sge() doesn't exactly duplicate the side effects of
ipath_copy_sge() if num_sge > 1 since it doesn't decrement ss->num_sge.
This could result in the sg_list being accessed out of bounds.
Since ipath_skip_sge() is almost always called with num_sge == 1,
the original "optimization" is almost never used.

C13-18.1.1 (prevent duplicate requests and responses sent on the

Subject: [PATCH 620/793] [DCCP]: Fix default sequence window size
When using the default sequence window size (100) I got the following in
my logs:

Jun 22 14:24:09 localhost kernel: [ 1492.115147] DCCP: Step 6 failed for
DATA packet, (LSWL(6279674225) <= P.seqno(6279674750) <=

P.ackno(1125899906842620) <= S.AWH(18798206549), sending SYNC...
I went to alter the default sysctl and it didn't take for new sockets.
Below patch fixes this.
I think the default is too low but it is what the DCCP spec specifies.
As a side effect of this my rx speed using iperf goes from about 2.8 Mbits/sec
to 3.5. This is still far too slow but it is a step in the right direction.
Compile tested only for IPv6 but not particularly complex change.

In PSCHED_TADD and PSCHED_TADD2, if delta is less than tv.tv_usec (so,
less than USEC_PER_SEC too) then tv_res will be smaller than tv. The
affectation "(tv_res).tv_usec = __delta;" is wrong. The fix is to
revert to the original code before
4ee303dfeac6451b402e3d8512723d3a0f861857 and change the 'if' in
'while'.

Subject: [PATCH 622/793] [Bluetooth] Correct RFCOMM channel MTU for broken
implementations
Some Bluetooth RFCOMM implementations try to negotiate a bigger channel
MTU than we can support for a particular session. The maximum MTU for
a RFCOMM session is limited through the L2CAP layer. So if the other
side proposes a channel MTU that is bigger than the underlying L2CAP
MTU, we should reduce it to the L2CAP MTU of the session minus five
bytes for the RFCOMM headers.

ARCH_IQ80331 and MACH_IQ80332 can be enabled at the same time but a
header file makes certain IRQ definitions conditional, leading to
the following compilation error when both platforms are enabled:
arch/arm/mach-iop3xx/iq80332-pci.c: In function 'iq80332_map_irq':
arch/arm/mach-iop3xx/iq80332-pci.c:54: error: 'IRQ_IQ80332_INTA' undeclared (first use in this function)

Subject: [PATCH 628/793] [IPV6] xfrm6_tunnel: Delete debugging code.
It doesn't compile, and it's dubious in several regards:
1) is enabled by non-Kconfig controlled CONFIG_* value
(noted by Randy Dunlap)
2) XFRM6_TUNNEL_SPI_MAGIC is defined after it's first use
3) the debugging messages print object pointer addresses
which have no meaning without context
So let's just get rid of it.

Subject: [PATCH 634/793] [SCSI] esp: Fix build.
The data_cmd[] member got deleted, so do not use it any more. Scsi
commands do not have their ->cmd[] overwritten temporary to probe for
status after an error before retrying.

Subject: [PATCH 639/793] [NETFILTER]: xt_pkttype: fix mismatches on locally
generated packets
Locally generated broadcast and multicast packets have pkttype set to
PACKET_LOOPBACK instead of PACKET_BROADCAST or PACKET_MULTICAST. This
causes the pkttype match to fail to match packets of either type.
The below patch remedies this by using the daddr as a hint as to
broadcast|multicast. While not pretty, this seems like the only way
to solve the problem short of just noting this as a limitation of the
match.
This resolves netfilter bugzilla #484

+ bridge. Their only use is to enable bridge output port filtering

Subject: [PATCH 646/793] [PATCH] cfq-iosched: don't use a hard jiffies value,
translate from msecs
The CIC_SEEKY() test really wants to use the minimum of either:
- 2 msecs (not jiffies)
- or, the pending slice time
So code it like that.

Subject: [PATCH 647/793] [POWERPC] fix up front-LED Kconfig
This patch fixes the front-LED Kconfig issues I introduced while
creating it. Apparently having a dependency isn't enough to have the
select not evaluated or something like that.
The patch also changes the default configuration for pmac32 select the
default for the LED to be the IDE trigger. While I was at it, I
completely updated the defconfig and also added snd-aoa to it.

Subject: [PATCH 648/793] [POWERPC] Workaround Pegasos incorrect ISA "ranges"
The Pegasos firmware doesn't create a valid "ranges" property for the
ISA bridge, thus causing translation of ISA addresses and IO ports to
fail. This fixes it, thus re-enabling proper early serial console to
work on Pegasos.

Subject: [PATCH 650/793] [POWERPC] Fix non-MPIC CHRPs with CONFIG_SMP set
Pseudo-CHRP machines like Pegasos without an MPIC would crash at boot if
CONFIG_SMP was set because the "smp_ops" pointer was set to MPIC related
ops unconditionally. This patch makes it NULL on machines that don't
support SMP and provides proper default behaviour in the callers when
smp_ops is NULL.

Subject: [PATCH 652/793] [POWERPC] Fix legacy_serial.c error handling on 32
bits
The code in legacy_serial.c wouldn't properly compare OF translation
results against OF_BAD_ADDR as it's using a phys_addr_t which is 32
bits on some 32-bit powerpc platforms. This fixes it by always using
a u64 which is what is returned by the OF parsing routines. It also
makes translation failure harmless for ISA serial ports. If they
can't translate, we can't use the UART early, but we can still let the
8250 driver use it later on by using IO port accessors.

Subject: [PATCH 653/793] [POWERPC] More offb/bootx fixes
There were still some issues with offb when BootX doesn't provide a
proper display node, this fixes them. This also re-instates the
palette hacks that were disabled a couple of kernel versions ago when
I converted to the new OF parsing, and shuffles some functions around
to avoid prototypes.

Subject: [PATCH 654/793] [POWERPC] Fix mem= handling when the memory limit is
> RMO size
There's a bug in my cleaned up mem= handling, if the memory limit is
larger than the RMO size we'll erroneously enlarge the RMO size.
Fix is to only change the RMO size if the memory limit is less than
the current RMO value.

Subject: [PATCH 658/793] [IPV4] ipmr: ip multicast route bug fix.
IP multicast route code was reusing an skb which causes use after free
and double free.
From: Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>
Note, it is real skb_clone(), not alloc_skb(). Equeued skb contains
the whole half-prepared netlink message plus room for the rest.
It could be also skb_copy(), if we want to be puristic about mangling
cloned data, but original copy is really not going to be used.

Subject: [PATCH 659/793] [IPV4/IPV6]: Setting 0 for unused port field in RAW
IP recvmsg().
From: Tetsuo Handa from-linux-kernel@i-love.sakura.ne.jp
The recvmsg() for raw socket seems to return random u16 value
from the kernel stack memory since port field is not initialized.
But I'm not sure this patch is correct.
Does raw socket return any information stored in port field?
[ BSD defines RAW IP recvmsg to return a sin_port value of zero.
This is described in Steven's TCP/IP Illustrated Volume 2 on
page 1055, which is discussing the BSD rip_input() implementation. ]

Subject: [PATCH 660/793] [PATCH] Reorganize the cpufreq cpu hotplug locking to
not be totally bizare
The patch below moves the cpu hotplugging higher up in the cpufreq
layering; this is needed to avoid recursive taking of the cpu hotplug
lock and to otherwise detangle the mess.
The new rules are:
1. you must do lock_cpu_hotplug() around the following functions:
__cpufreq_driver_target
__cpufreq_governor (for CPUFREQ_GOV_LIMITS operation only)
__cpufreq_set_policy
2. governer methods (.governer) must NOT take the lock_cpu_hotplug()
lock in any way; they are called with the lock taken already
3. if your governer spawns a thread that does things, like calling
__cpufreq_driver_target, your thread must honor rule #1.
4. the policy lock and other cpufreq internal locks nest within
the lock_cpu_hotplug() lock.
I'm not entirely happy about how the __cpufreq_governor rule ended up
(conditional locking rule depending on the argument) but basically all
callers pass this as a constant so it's not too horrible.
The patch also removes the cpufreq_governor() function since during the
locking audit it turned out to be entirely unused (so no need to fix it)
The patch works on my testbox, but it could use more testing
(otoh... it can't be much worse than the current code)

Subject: [PATCH 661/793] [PATCH] fix compile regression for a few scsi drivers
This fixes three drivers to compile again after my patch that removes
the data_cmnd member from struct scsi_cmnd.
The fas216 change is trivial, it should have been using ->cmnd all the
time.
NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing
something odd, it should only have looked at ->cmnd before not the saved
copy that is kept for the error handlers sake. Note that it really
should deal with the sync setting themselves but use the generic domain
validation code that get this right - but that's for later let's push
this simple compile fix for now.
And sorry for the late fix for this, I have been busy with OLS and
associated activities last week.

Subject: [PATCH 665/793] [S390] permanent subchannel busy conditions may cause
I/O stall
In special conditions where a subchannel rejects the HALT I/O-
instruction with a busy indication (cc 2), I/O may stall.
I/O request termination logic retries HALT I/O indefinitely
because it expects HALT I/O to alter the subchannel status which
is not true when cc 2 is returned.
In case of a busy indication, try CLEAR I/O instruction immediately.

Subject: [PATCH 670/793] [PATCH] softmac: do shared key auth in workqueue
Johann Uhrmann reported a bcm43xx crash and Michael Buesch tracked
it down to a problem with the new shared key auth code (recursive
calls into the driver)
This patch (effectively Michael's patch with a couple of small
modifications) solves the problem by sending the authentication
challenge response frame from a workqueue entry.
I also removed a lone \n from the bcm43xx messages relating to
authentication mode - this small change was previously discussed but
not patched in.

Subject: [PATCH 671/793] [PATCH] orinoco: fix setting transmit key only
When determining whether there's a key to set or not, orinoco should be
looking at the key length, not the key data. Otherwise confusion reigns
when trying to set TX key only, passing in zero-length key, but non-NULL
pointer. Key length takes precedence over non-NULL key data.

Subject: [PATCH 674/793] [POWERPC] Xserve G5 thermal control fixes
The thermal control for the Xserve G5s had a few issues. For one, the
way to program the RPM fans speeds into the FCU is different between it
and the desktop models, which I didn't figure out until recently, and it
was missing a control loop for the slots fan, running it too fast. Both
of those problems were causing the machine to be much more noisy than
necessary. This patch also changes the fixed value of the slots fan for
desktop G5s to 40% instead of 50%. It seems to still have a pretty good
airflow that way and is much less noisy.

Subject: [PATCH 675/793] [POWERPC] Add cpufreq support for Xserve G5
The Xserve G5 are capable of frequency switching like other desktop G5s.
This enables it. It also fix a Kconfig issue which prevented from
building the G5 cpufreq support if CONFIG_PMAC_SMU was not set (the
first version of that driver only worked with SMU based macs, but this
isn't the case anymore).

Subject: [PATCH 690/793] [POWERPC] force 64bit mode in fwnmi handlers to
workaround firmware bugs
The firmware of POWER4 and JS20 systems does not switch the cpu to 64bit
mode when the registered system_reset and machine_check handlers get called.
If a 32bit process runs on that cpu at the time of the event, the cpu
remains in 32bit mode. xmon and kdump can not deal with it, the result is
an error like 'Bad kernel stack pointer fff2aad0 at 3200'.
xmon just loses some register info, but booting the kdump kernel usually fails.
Both handlers are not hot paths. Duplicate the EXCEPTION_PROLOG_PSERIES macro
and add two instructions to switch to 64bit:
li r11,5;
rldimi r10,r11,61,0;

a race - when a user program jumps to a kernel lock address and
a NMI happens before the illegal page fault exception is raised
and the program has a unmapped esp or ebp then the kernel could
oops. NMIs have a higher priority than exceptions so that could
happen.
Add user_mode checks to i386/x86-64 profile_pc to prevent that.

Subject: [PATCH 693/793] [PATCH] x86_64: Don't clobber r8-r11 in int 0x80
handler
When int 0x80 is called from long mode r8-r11 would leak out of the
kernel (or rather they would be filled with some values from
the kernel stack). I don't think it's a security issue because
the values come from the fixed stack frame which should be near
always user registers from a previous interrupt.
Still better fix it.
Longer term the register save macros need to be cleaned up
to avoid such mistakes in the future.
Original analysis from Richard Brunner, fix by me.

Subject: [PATCH 694/793] [PATCH] x86_64: Enlarge debug stack for nested
kprobes
In x86_64 platform, INT1 and INT3 trap stack is IST stack called DEBUG_STACK,
when INT1/INT3 trap happens, system will switch to DEBUG_STACK by hardware.
Current DEBUG_STACK size is 4K, when int1/int3 trap happens, kernel will
minus current DEBUG_STACK IST value by 4k. But if int3/int1 trap is nested,
it will destroy other vector's IST stack. This patch modifies this, it sets
DEBUG_STACK size as 8K and allows two level of nested int1/int3 trap.
Kprobe DEBUG_STACK may be nested, because kprobe handler may be probed
by other kprobes.
Thanks jbeulich for pointing out error in the first patch.
[AK: nested kprobes are pretty dubious. Hopefully one nest
will be enough. This will cost 8K per CPU (4K more than before)]

Subject: [PATCH 695/793] [PATCH] x86_64: Dump leftover backtrace entries when
dwarf2 unwinder got stuck
The dwarf2 unwinder currently often gets stuck because a lot
of assembly code doesn't have proper dwarf2 annotiation yet.
This currently often happens with __down. Should fix this by
adding proper dwarf2 annotation to all inline assembly. However
until that's done we need a quick fix for 2.6.18 to avoid
incomplete backtraces.
So when this happens dump the rest of the stack with the old unwinder
instead of silently not dumping it. There was already a optional
"both" mode that dumped both, but that was too ugly.
I also clarified the headers for the different backtraces a bit.
Also add a clear error message for missing dwarf2
annotation that people can work on.
And I removed a dead variable left over from Ingo's changes.

Subject: [PATCH 699/793] [PATCH] pi-futex: robust-futex exit
Fix robust PI-futexes to be properly unlocked on unexpected exit.
For this to work the kernel has to know whether a futex is a PI or a
non-PI one, because the semantics are different. Since the space in
relevant glibc data structures is extremely scarce, the best solution is
to encode the 'PI' information in bit 0 of the robust list pointer.
Existing (non-PI) glibc robust futexes have this bit always zero, so the
ABI is kept. New glibc with PI-robust-futexes will set this bit.

Always do a dummy RDMA after loading the firmware to work around

This is so cheap as to be almost free, and should never have been

Subject: [PATCH 702/793] [ARM] 3736/1: xscale: don't mis-report 80219 as an
iop32x
Patch from Lennert Buytenhek
The IOP 80219 xscale CPU is a stripped down version of the IOP32x.
But the fact that the 80219 and IOP32x are very similar doesn't mean
that they need to share a cpu table entry. It's also somewhat confusing
for the end user to see the 80219 reported as an IOP32x, so this patch
splits the IOP32x cpu table entry to make a separate entry for the
80219.

Patch from George G. Davis
As reported by various folks on the ARM Linux kernel mailing list,
the video-buf.ko driver has undefined references on all ARM machines
which use it as observed during `make modules`:
Warning: "v4wb_clear_user_page" [drivers/media/video/video-buf.ko] undefined!
Similar warnings exist for all ARM machines which use this driver.
So this change adds the missing EXPORT_SYMBOLs to allow using this
driver as a module.

Subject: [PATCH 708/793] [PATCH] x86_64: Calgary IOMMU - Multi-Node NULL
pointer dereference fix
Calgary hits a NULL pointer dereference when booting in a multi-chassis
NUMA system. See Redhat bugzilla number 198498, found by Konrad
Rzeszutek (konradr@redhat.com).
There are many issues that had to be resolved to fix this problem.
Firstly when I originally wrote the code to handle NUMA systems, I
had a large misunderstanding that was not corrected until now. That was
that I thought the "number of nodes online" referred to number of
physical systems connected. So that if NUMA was disabled, there
would only be 1 node and it would only show that node's PCI bus.
In reality if NUMA is disabled, the system displays all of the
connected chassis as one node but is only ignorant of the delays
in accessing main memory. Therefore, references to num_online_nodes()
and MAX_NUMNODES are incorrect and need to be set to the maximum
number of nodes that can be accessed (which are 8). I created a
variable, MAX_NUM_CHASSIS, and set it to 8 to fix this.
Secondly, when walking the PCI in detect_calgary, the code only
checked the first "slot" when looking to see if a device is present.
This will work for most cases, but unfortunately it isn't always the
case. In the NUMA MXE drawers, there are USB devices present on the
3rd slot (with slot 1 being empty). So, to work around this, all
slots (up to 8) are scanned to see if there are any devices present.
Lastly, the bus is being enumerated on large systems in a different
way the we originally thought. This throws the ugly logic we had
out the window. To more elegantly handle this, I reorganized the
kva array to be sparse (which removed the need to have any bus number
to kva slot logic in tce.c) and created a secondary space array to
contain the bus number to phb mapping.
With these changes Calgary boots on an x460 with 4 nodes with and
without NUMA enabled.

Subject: [PATCH 710/793] [PATCH] x86_64: Fix swiotlb=force
It was broken before. But having it is important as possible hardware
bug workaround.
And previously there was no way to force swiotlb if there is another IOMMU.
Side effect is that iommu=force won't force swiotlb anymore even if there
isn't another IOMMU.

On the JS21 systems, they have the SPLPAR hypertas set, but are not SMT
capable. So, they are not making the H_CEDE call. This is causing the
hypervisor to have to queue up work for the hdecr, taking an excessive
amount of time in maintenance code, and causing jitter on the box.
Making the H_CEDE call helps alleviate that problem.

Subject: [PATCH 717/793] [PATCH] ext3: avoid triggering ext3_error on bad NFS
file handle
The inode number out of an NFS file handle gets passed eventually to
ext3_get_inode_block() without any checking. If ext3_get_inode_block()
allows it to trigger an error, then bad filehandles can have unpleasant
effect - ext3_error() will usually cause a forced read-only remount, or a
panic if `errors=panic' was used.
So remove the call to ext3_error there and put a matching check in
ext3/namei.c where inode numbers are read off storage.

Subject: [PATCH 718/793] [PATCH] Process Events: Fix biarch compatibility
issue. use __u64 timestamp
Events sent by Process Events Connector from a 64-bit kernel are not binary
compatible with a 32-bit userspace program because the "timestamp" field
(struct timespec) is not arch independent. This affects the fields that
follow "timestamp" as they will be be off by 8 bytes.
This is a problem for 32-bit userspace programs running with 64-bit kernels
on ppc64, s390, x86-64.. any "biarch" system.
Matt had submitted a different solution to lkml as an RFC earlier. We have
since switched to a solution recommended by Evgeniy Polyakov.
This patch fixes the problem by changing the timestamp to be a __u64, which
stores the number of nanoseconds.
Tested on a x86_64 system with both 32 bit application and 64 bit
application and on a i386 system.

Subject: [PATCH 720/793] [PATCH] genirq: {en,dis}able_irq_wake() need
refcounting too
IRQs need refcounting and a state flag to track whether the the IRQ should
be enabled or disabled as a "normal IRQ" source after a series of calls to
{en,dis}able_irq(). For shared IRQs, the IRQ must be enabled so long as at
least one driver needs it active.
Likewise, IRQs need the same support to track whether the IRQ should be
enabled or disabled as a "wakeup event" source after a series of calls to
{en,dis}able_irq_wake(). For shared IRQs, the IRQ must be enabled as a
wakeup source during sleep so long as at least one driver needs it. But
right now they _don't have_ that refcounting ... which means sharing a
wakeup-capable IRQ can't work correctly in some configurations.
This patch adds the refcount and flag mechanisms to set_irq_wake() -- which
is what {en,dis}able_irq_wake() call -- and minimal documentation of what
the irq wake mechanism does.
Drivers relying on the older (broken) "toggle" semantics will trigger a
warning; that'll be a handful of drivers on ARM systems.

This patch reverses the default behaviour to improve coverage testing. It
can be removed late in the kernel development cycle if its believed users
shouldn't have to incur any cost if they don't want delay accounting. Or
it can be retained forever if the utility of the stats is deemed common
enough to warrant keeping the feature on.

Subject: [PATCH 724/793] [PATCH] Fix ppc32 zImage inflate
The recent zlib update (commit 4f3865fb57a04db7cca068fed1c15badc064a302)
broke ppc32 zImage decompression as it tries to decompress to address zero
and the updated zlib_inflate checks that strm->next_out isn't a null
pointer.
This little patch fixes it.

Subject: [PATCH 726/793] [PATCH] knfsd: Fix stale file handle problem with
subtree_checking.
A recent commit (7fc90ec93a5eb71f4b08403baf5ba7176b3ec6b1) moved the
call to nfsd_setuser out of the 'find a dentry for a filehandle' branch
of fh_verify so that it would always be called.
This had the unfortunately side-effect of moving *after* the call to
decode_fh, so the prober fsuid was not set when nfsd_acceptable was called,
the 'permission' check did the wrong thing.
This patch moves the nfsd_setuser call back where it was, and add as call
in the other branch of the if.

The kprobe-booster's safety check against preemption does not work well
now, because the preemption count has been modified by read_rcu_lock() in
atomic_notifier_call_chain() before we check it. So, I'd like to prevent
boosting kprobe temporarily if the kernel is preemptable.
Now we are searching for the good solution.

Subject: [PATCH 734/793] [PATCH] IA64: kprobe invalidate icache of jump buffer
Kprobe inserts breakpoint instruction in probepoint and then jumps to
instruction slot when breakpoint is hit, the instruction slot icache must
be consistent with dcache. Here is the patch which invalidates instruction
slot icache area.
Without this patch, in some machines there will be fault when executing
instruction slot where icache content is inconsistent with dcache.

Subject: [PATCH 737/793] [PATCH] invalidate_bdev() speedup
We can immediately bail from invalidate_bdev() if the blockdev has no
pagecache.
This solves the huge IPI storms which hald is causing on the big ia64
machines when it polls CDROM drives.

Subject: [PATCH 738/793] [PATCH] IDE: Touch NMI watchdog during resume from
STR
When resuming from suspend-to-RAM, the NMI watchdog detects a lockup in
ide_wait_not_busy. Here's a screenshot of the trace taken by a digital
camera: http://www.uamt.feec.vutbr.cz/rizeni/pom/DSC03510-2.JPG
Let's touch the NMI watchdog in ide_wait_not_busy. The system then resumes
correctly from STR.

Subject: [PATCH 741/793] [PATCH] nbd: Abort request on data reception failure
When reading from nbd device, we need to receive all the data after
receiving reply packet from the server - otherwise such request will never
be ended.
If socket is closed right after accepting reply control packet and in the
middle of waiting for read data, nbd_read_stat() returns NULL and
nbd_end_request() is not called.
This patch fixes it.

Subject: [PATCH 743/793] [PATCH] panic_on_oops: remove ssleep()
This patch is part of an effort to unify the panic_on_oops behaviour across
all architectures that implement it.
It was pointed out to me by Andi Kleen that if an oops has occured in
interrupt context, then calling sleep() in the oops path will only cause a
panic, and that it would be really better for it not to be in the path at
all.
This patch removes the ssleep() call and reworks the console message
accordinly. I have a slght concern that the resulting console message is
too long, feedback welcome.
For powerpc it also unifies the 32bit and 64bit behaviour.
Fror x86_64, this patch only updates the console message, as ssleep() is
already not present.

Subject: [PATCH 744/793] [PATCH] cpu hotplug: replace __devinit* with
__cpuinit* for cpu notifications
Few of the callback functions and notifier blocks that are associated with cpu
notifications incorrectly have __devinit and __devinitdata. They should be
__cpuinit and __cpuinitdata instead.
It makes no functional difference but wastes text area when CONFIG_HOTPLUG is
enabled and CONFIG_HOTPLUG_CPU is not.
This patch fixes all those instances.

+You need to call register_cpu_notifier() from your init function.
+Init functions could be of two types:
+1. early init (init function called when only the boot processor is online).
+2. late init (init function called _after_ all the CPUs are online).
-In your init function,
+For the first case, you should add the following to your init function

+For the second case, you should add the following to your init function
+
+ register_hotcpu_notifier(&foobar_cpu_notifier);

You can fail PREPARE notifiers if something doesn't work to prepare resources.
This will stop the activity and send a following CANCELED event back.

Subject: [PATCH 747/793] [PATCH] fix bad macro param in timer.c
We have
#define INDEX(N) (base->timer_jiffies >> (TVR_BITS + N * TVN_BITS)) & TVN_MASK
and it's used via
list = varray[i + 1]->vec + (INDEX(i + 1));
So, due to underparenthesisation, this INDEX(i+1) is now a ... (TVR_BITS + i
+ 1 * TVN_BITS)) ...
So this bugfix changes behaviour. It worked before by sheer luck:
"If i was anything but 0, it was broken. But this was only used by
s390 and arm. Since it was for the next interrupt, could that next
interrupt be a problem (going into the second cascade)? But it was
probably seldom wrong. That is, this would fail if the next
interrupt was in the second cascade, and was wrapped. Which may
never of happened. Also if it did happen, it would have just missed
the interrupt.
If an interrupt was missed, and no one was there to miss it, was it
really missed :-)"

In cond_resched_lock() it calls __resched_legal() before dropping the spin
lock. __resched_legal() will always finds the preempt_count non-zero and
will prevent the call to __cond_resched().
The attached patch adds a parameter to __resched_legal() with the expected
preempt_count value.

Subject: [PATCH 752/793] [PATCH] Add DocBook documentation for workqueue
functions
kernel/workqueue.c was omitted from generating kernel documentation. This
adds a new section "Workqueues and Kevents" and adds documentation for some
of the functions.
Some functions in this file already had DocBook-style comments, now they
finally become visible.

Subject: [PATCH 760/793] [PATCH] pi-futex: missing pi_waiters plist
initialization
Initialize init task's pi_waiters plist. Otherwise cpu hotplug of cpu 0
might crash, since rt_mutex_getprio() accesses an uninitialized list head.
call chain which led to crash:
take_cpu_down
sched_idle_next
__setscheduler
rt_mutex_getprio
Using PLIST_HEAD_INIT in the INIT_TASK macro doesn't work unfortunately,
since the pi_waiters member is only conditionally present.

patch to add the linux-mm mailing list to the MAINTAINERS file.
Also, since mm is so broad, it doesn't have a single person to maintain it,
and thus no maintainer is listed. I also left the status as Maintained,
since it obviously is.

Subject: [PATCH 762/793] [PATCH] inotify: fix deadlock found by lockdep
This is a real deadlock, a nice complex one:
(warning: long explanation follows so that Andrew can have a complete
patch description)
it's an ABCDA deadlock:
A iprune_mutex
B inode->inotify_mutex
C ih->mutex
D dev->ev_mutex
The AB relationship comes straight from invalidate_inodes()
int invalidate_inodes(struct super_block * sb)
{
int busy;
LIST_HEAD(throw_away);
mutex_lock(&iprune_mutex);
spin_lock(&inode_lock);
inotify_unmount_inodes(&sb->s_inodes);
where inotify_umount_inodes() takes the
mutex_lock(&inode->inotify_mutex);
The BC relationship comes directly from inotify_find_update_watch():
s32 inotify_find_update_watch(struct inotify_handle *ih, struct inode *inode,
u32 mask)
{
...
mutex_lock(&inode->inotify_mutex);
mutex_lock(&ih->mutex);
The CD relationship comes from inotify_rm_wd:
inotify_rm_wd does
mutex_lock(&inode->inotify_mutex);
mutex_lock(&ih->mutex)
and then calls inotify_remove_watch_locked() which calls
notify_dev_queue_event() which does
mutex_lock(&dev->ev_mutex);
(this strictly is a BCD relationship)
The DA relationship comes from the most interesting part:
[<ffffffff8022d9f2>] shrink_icache_memory+0x42/0x270
[<ffffffff80240dc4>] shrink_slab+0x11d/0x1c9
[<ffffffff802b5104>] try_to_free_pages+0x187/0x244
[<ffffffff8020efed>] __alloc_pages+0x1cd/0x2e0
[<ffffffff8025e1f8>] cache_alloc_refill+0x3f8/0x821
[<ffffffff8020a5e5>] kmem_cache_alloc+0x85/0xcb
[<ffffffff802db027>] kernel_event+0x2e/0x122
[<ffffffff8021d61c>] inotify_dev_queue_event+0xcc/0x140
inotify_dev_queue_event schedules a kernel_event which does a
kmem_cache_alloc( , GFP_KERNEL) which may try to shrink slabs, including
the inode cache .. which then takes iprune_mutex.
And voila, there is an AB, a BC, a CD relationship (even a direct BCD),
and also now a DA relationship -> a circular type AB-BA deadlock but
involving 4 locks.
The solution is simple: kernel_event() is NOT allowed to use GFP_KERNEL,
but must use GFP_NOFS to not cause recursion into the VFS.

Subject: [PATCH 763/793] [PATCH] Fix swsusp with PNP BIOS
swsusp is unable to suspend my machine (DTK FortisPro TOP-5A notebook) with
kernel 2.6.17.5 because it's unable to suspend PNP device 00:16 (mouse).
The problem is in PNP BIOS. pnp_bus_suspend() calls pnp_stop_dev() for the
device if the device can be disabled according to pnp_can_disable(). The
problem is that pnpbios_disable_resources() returns -EPERM if the device is
not dynamic (!pnpbios_is_dynamic()) but insert_device() happily sets
PNP_DISABLE capability/flag even if the device is not dynamic. So we try
to disable non-dynamic devices which will fail. This patch prevents
insert_device() from setting PNP_DISABLE if the device is not dynamic and
fixes suspend on my system.

Subject: [PATCH 770/793] [PATCH] Reducing local_bh_enable/disable overhead in
irqtrace
The recent changes from irqtrace feature has added overheads to
local_bh_disable and local_bh_enable that reduces UDP performance across
x86_64 and IA64, even though IA64 does not support the irqtrace feature.
Patch in question is
[PATCH]lockdep: irqtrace subsystem, core
http://www.kernel.org/git/?p=linux/kernel/git/torvalds/linux-2.6.git;a=c
ommit;h=de30a2b355ea85350ca2f58f3b9bf4e5bc007986
Prior to this patch, local_bh_disable was a short macro. Now it is a
function which calls __local_bh_disable with added irq flags save and
restore. The irq flags save and restore were also added to
local_bh_enable, probably for injecting the trace irqs code.
This overhead is on the generic code path across all architectures. On a
IA_64 test machine (Itanium-2 1.6 GHz) running a benchmark like netperf's
UDP streaming test, the added overhead results in a drop of 3% in
throughput, as udp_sendmsg calls the local_bh_enable/disable several times.
Other workloads that have heavy usages of local_bh_enable/disable could
also be affected. The patch ideally should not have affected IA-64
performance as it does not have IRQ tracing support. A significant portion
of the overhead is in the added irq flags save and restore, which I think
is not needed if IRQ tracing is unused. A suggested patch is attached
below that recovers the lost performance. However, the "ifdef"s in the
patch are a bit ugly.

In order to prevent Doc Rot, this patch adds a reference to the design
document for rtmutex.c in rtmutex.c. So when someone needs to update or
change the design of that file they will know that a document actually
exists that explains the design (helping them change it), and hopefully
that they will update the document if they too change the design.

Subject: [PATCH 776/793] [PATCH] vDSO hash-style fix
The latest toolchains can produce a new ELF section in DSOs and
dynamically-linked executables. The new section ".gnu.hash" replaces
".hash", and allows for more efficient runtime symbol lookups by the
dynamic linker. The new ld option --hash-style={sysv|gnu|both} controls
whether to produce the old ".hash", the new ".gnu.hash", or both. In some
new systems such as Fedora Core 6, gcc by default passes --hash-style=gnu
to the linker, so that a standard invocation of "gcc -shared" results in
producing a DSO with only ".gnu.hash". The new ".gnu.hash" sections need
to be dealt with the same way as ".hash" sections in all respects; only the
dynamic linker cares about their contents. To work with older dynamic
linkers (i.e. preexisting releases of glibc), a binary must have the old
".hash" section. The --hash-style=both option produces binaries that a new
dynamic linker can use more efficiently, but an old dynamic linker can
still handle.
The new section runs afoul of the custom linker scripts used to build vDSO
images for the kernel. On ia64, the failure mode for this is a boot-time
panic because the vDSO's PT_IA_64_UNWIND segment winds up ill-formed.
This patch addresses the problem in two ways.
First, it mentions ".gnu.hash" in all the linker scripts alongside ".hash".
This produces correct vDSO images with --hash-style=sysv (or old tools),
with --hash-style=gnu, or with --hash-style=both.
Second, it passes the --hash-style=sysv option when building the vDSO
images, so that ".gnu.hash" is not actually produced. This is the most
conservative choice for compatibility with any old userland. There is some
concern that some ancient glibc builds (though not any known old production
system) might choke on --hash-style=both binaries. The optimizations
provided by the new style of hash section do not really matter for a DSO
with a tiny number of symbols, as the vDSO has. If someone wants to use
=gnu or =both for their vDSO builds and worry less about that
compatibility, just change the option and the linker script changes will
make any choice work fine.

happened at the next clock tick.

Subject: [PATCH 779/793] [PATCH] fuse: use jiffies_64
It is entirely possible (though rare) that jiffies half-wraps around, while a
dentry/inode remains in the cache. This could mean that the dentry/inode is
not invalidated for another half wraparound-time.
To get around this problem, use 64-bit jiffies. The only problem with this is
that dentry->d_time is 32 bits on 32-bit archs. So use d_fsdata as the high
32 bits. This is an ugly hack, but far simpler, than having to allocate
private data just for this purpose.
Since 64-bit jiffies can be assumed never to wrap around, simple comparison
can be used, and a zero time value can represent "invalid".

+----------------------

+Recent kernels have support for populating a ramdisk from a compressed cpio
+archive, on such systems, the creation of a ramdisk image doesn't need to
+involve special block devices or loopbacks, you merely create a directory on
+disk with the desired initrd content, cd to that directory, and run (as an
+example):

vxfs_readdir
Commit 7b2fd697427e73c81d5fa659efd91bd07d303b0e in the historical GIT tree
stopped calling the readdir member of a file_operations struct with the big
kernel lock held, and fixed up all the readdir functions to do their own
locking. However, that change added calls to unlock_kernel() in
vxfs_readdir, but no call to lock_kernel(). Fix this by adding a call to
lock_kernel().

Subject: [PATCH 788/793] [PATCH] 9p: fix fid behavior on failed remove
Based on a bug report from Russ Ross <russruss@gmail.com>
According to the spec:
"The remove request asks the file server both to remove the file
represented by fid and to clunk the fid, even if the remove fails."
but the Linux client seems to expect the fid to be valid after a failed
remove attempt. Specifically, I'm getting this behavior when attempting to
remove a non-empty directory.

Subject: [PATCH 789/793] [PATCH] fbdev: statically link the framebuffer
notification functions
The backlight and lcd subsystems can be notified by the framebuffer layer
of blanking events. However, these subsystems, as a whole, can function
independently from the framebuffer layer. But in order to enable to the
lcd and backlight subsystems, the framebuffer has to be compiled also,
effectively sucking in a huge amount of unneeded code.
To prevent dependency problems, separate out the framebuffer notification
mechanism from the framebuffer layer and permanently link it to the kernel.

Subject: [PATCH 790/793] [PATCH] radeonfb sleep fixes
Many IBM Thinkpad T4* models and some R* and X* with radeon video cards draw
too much power when suspended to RAM, reducing drastically the battery
lifetime. The solution is to enable suspend-to-D2 on these machines. They
are whitelisted through their subsystem vendor/device ID. This fixes
http://bugzilla.kernel.org/show_bug.cgi?id=3022
The patch introduces a framework to alter the pm_mode and reinit_func fields
of the radeonfb_info structure based on a whitelist. This should facilitate
future hardware-dependent workarounds. The workaround for the Samsung P35
that is already in the radeonfb code has been rewritten using this framework.
The behavior can be overridden with module options:
i) video=radeonfb:force_sleep=1
enable suspend-to-D2 also on non-whitelisted machines (useful for
testing new notebook models),
ii) video=radeonfb:ignore_devlist=1
Disable checking the whitelist and do not apply any workarounds.

From 4b755999d6e0c1d988fb448289abb6c226cd8c36 Mon Sep 17 00:00:00 2001
From: Michael Hanselmann <linux-kernel@hansmi.ch>
Date: Sun, 30 Jul 2006 03:04:19 -0700
Subject: [PATCH 791/793] [PATCH] powermac: More powermac backlight fixes
This patch fixes several problems:
- The legacy backlight value might be set at interrupt time. Introduced
a worker to prevent it from directly calling the backlight code.
- via-pmu allows the backlight to be grabbed, in which case we need to
prevent other kernel code from changing the brightness.
- Don't send PMU requests in via-pmu-backlight when the machine is about
to sleep or waking up.
- More Kconfig fixes.

Subject: [PATCH 792/793] [PATCH] nvidiafb: remove redundant CONFIG_PCI check
CONFIG_FB_NVIDIA already depends on CONFIG_PCI in drivers/video/Kconfig.
Driver does an extra ``sanity check'' which is then redundant.

Subject: [PATCH 793/793] [PATCH] rivafb/nvidiafb: race between
register_framebuffer and *_bl_init
Since we now use the generic backlight infrastructure, I think we need to
call rivafb_bl_init before calling register_framebuffer since otherwise
rivafb_bl_init might race with the framebuffer layer already opening the
device and setting up the video mode. In this case we might end up with a
not yet fully intialized backlight (info->bl_dev still NULL) when calling
riva_bl_set_power via rivafb_set_par/rivafb_load_video_mode and the kernel
dies without any further notice during boot.
This fixes booting current git on a PB 6,1. In this case radeonfb/atyfb
would be affected too - I can fix that too but don't have any hardware to
test this on.
