Allow fbcon to select the primary display adapter using the fb_is_primary_device() arch-specific helper. If a a primary adapter is detected, fbcon will unbind the old adapter from the VT layer, then rebind using the new adapter. This requires that bind_/unbind_con_driver() be made public. Because this feature may produce unexpected behavior (from the user's POV), this must be explicitly enabled in Kconfig. [akpm@linux-foundation.org: export unbind_con_driver] Signed-off-by:

On large memory configuration with not so fast CPUs the NMI watchdog is triggered when memory addresses are being gathered and printed. The code paths for Alt-SysRq-t are sprinkled with touch_nmi_watchdog in various places but not in this routine (or in the loop that utilizes this function). The patch has been tested for regression on large CPU+memory configuration (128 logical CPUs + 224 GB) and 1,2,4,16-CPU sockets with various memory sizes (1,2,4,6,20).

KSYM_NAME_LEN is peculiar in that it does not include the space for the trailing '\0', forcing all users to use KSYM_NAME_LEN + 1 when allocating buffer. This is nonsense and error-prone. Moreover, when the caller forgets that it's very likely to subtly bite back by corrupting the stack because the last position of the buffer is always cleared to zero. This patch increments KSYM_NAME_LEN by one and updates code accordingly. * off-by-one bug in asm-powerpc/kprobes.h::kprobe_lookup_name() macro is fixed. * Where MODULE_NAME_LEN and KSYM_NAME_LEN were used together, MODULE_NAME_LEN was treated as if it didn't include space for the trailing '\0'. Fix it. Signed-off-by:

This is a driver for the SB1250 DUART, a dual serial port implementation included in the Broadcom family of SOCs descending from the SiByte SB1250 MIPS64 chip multiprocessor. It is a new implementation replacing the old-fashioned driver currently present in the linux-mips.org tree. It supports all the usual features one would expect from a(n asynchronous) serial driver, including modem line control (as far as hardware supports it -- there is edge detection logic missing from the DCD and RI lines and the driver does not implement polling of these lines at the moment), the serial console, BREAK transmission and reception, including the magic SysRq. The receive FIFO threshold is not maintained though. The driver was tested with a SWARM board which uses a BCM1250 SOC (which is dual MIPS64 CMP) and has both ports of the single DUART implemented wired externally. Both were tested. Testing included using the ports as terminal lines at 1200bps (which is the ports minimum), 115200bps and a couple of random speeds inbetween. The modem lines were verified to operate correctly. No testing was performed with a use as a network interface, like with SLIP or PPP. Signed-off-by:

Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by:

This patch adds the kernelcore= parameter for x86. Once all patches are applied, a new command-line parameter exist and a new sysctl. This patch adds the necessary documentation. From: Yasunori Goto <y-goto@jp.fujitsu.com> When "kernelcore" boot option is specified, kernel can't boot up on ia64 because of an infinite loop. In addition, the parsing code can be handled in an architecture-independent manner. This patch uses common code to handle the kernelcore= parameter. It is only available to architectures that support arch-independent zone-sizing (i.e. define CONFIG_ARCH_POPULATES_NODE_MAP). Other architectures will ignore the boot parameter.

The instructions with format RX_URRD and SI_URD and instructions with a PC relative operand are not disassembled correctly. For RX_URRD and SI_URD instructions find_insn sets opfrag to code[0]. The mask byte of these two formats is 0x00. table->opfrag will never be identical to (opfrag & opmask) and no matching instruction will be found. Set the mask byte to 0xff to actually check byte 0 against the table. For PC relative instructions the (unsigned) offset value needs to be casted to an signed integer so that negative branch offsets are handled correctly. Signed-off-by:

The UMSDOS filesystem was removed back in 2.6.11, but some tiny bits stuck around. This patch removes the few remaining leftovers. The only things left behind after this are the entries in the CREDITS file and the ioctl number in Documentation/ioctl-number.txt as documentation. This third (hopefully final) version of the patch doesn't edit the arch/um/config.release file, since Jeff Dike pointed out to me that it should die completely, and asked me to remove it from my patch as he'll send in a seperate patch removing the file completely.

The current generic bug implementation has a call to dump_stack() in case a WARN_ON(whatever) gets hit. Since report_bug(), which calls dump_stack(), gets called from an exception handler we can do better: just pass the pt_regs structure to report_bug() and pass it to show_regs() in case of a warning. This will give more debug informations like register contents, etc... In addition this avoids some pointless lines that dump_stack() emits, since it includes a stack backtrace of the exception handler which is of no interest in case of a warning. E.g. on s390 the following lines are currently always present in a stack backtrace if dump_stack() gets called from report_bug(): [<000000000001517a>] show_trace+0x92/0xe8) [<0000000000015270>] show_stack+0xa0/0xd0 [<00000000000152ce>] dump_stack+0x2e/0x3c [<0000000000195450>] report_bug+0x98/0xf8 [<0000000000016cc8>] illegal_op+0x1fc/0x21c [<00000000000227d6>] sysc_return+0x0/0x10 Acked-by:

OpenVZ Linux kernel team has discovered the problem with 32bit quota tools working on 64bit architectures. In 2.6.10 kernel sys32_quotactl() function was replaced by sys_quotactl() with the comment "sys_quotactl seems to be 32/64bit clean, enable it for 32bit" However this isn't right. Look at if_dqblk structure: struct if_dqblk { __u64 dqb_bhardlimit; __u64 dqb_bsoftlimit; __u64 dqb_curspace; __u64 dqb_ihardlimit; __u64 dqb_isoftlimit; __u64 dqb_curinodes; __u64 dqb_btime; __u64 dqb_itime; __u32 dqb_valid; }; For 32 bit quota tools sizeof(if_dqblk) == 0x44. But for 64 bit kernel its size is 0x48, 'cause of alignment! Thus we got a problem. Attached patch reintroduce sys32_quotactl() function, that handles this and related situations.
