Alchemy SoC uart have got a non-standard divisor register that needs some special handling. This patch adds divisor read/write functions with test and special handling for Alchemy internal uart. Signed-off-by:

I've noticed that the 8250/Au1x00 driver (drivers/serial/8250_au1x00.c) doesn't claim UART memory ranges and uses wrong (KSEG1-based) UART addresses instead of the physical ones. Signed-off-by:

The locking for the uart_port is over complicated, and can be simplified if we introduce a flag to indicate that a port is "dead" and will be removed. This also helps the validator because it removes a case of non-nested unlock ordering. Signed-off-by:

This patch disables and saves local interrupts during hash_page processing for SPE contexts. We have to do it explicitly in the spu_irq_class_1_bottom function. For the interrupt handlers, we get the behaviour implicitly by using SA_INTERRUPT to disable interrupts while in the handler. Signed-off-by:

As reported in Bugzilla Bug 6406, resume from S3 results in a blank screen. For the IBM Thinkpad X30 using vesafb as the console driver, successful resume from S3 requires option acpi_sleep=s3_bios,s3_mode. Update documentation. I would presume that, in any hardware, using vesafb as the console driver will require as a minimum s3_mode. Signed-off-by:

Generate new sysfs-attribute 'uid' that contains an device specific unique identifier. This can be used to identity multiple ALIASES of the same physical device (PAV). In addition the sysfs-attributes 'vendor' (containing the manufacturer of the device) and 'alias' (identify alias or base device) is added. This is first part of PAV support in LPAR (also valid on zVM). Signed-off-by:

In case of an instruction processing damage (IPD) machine check in kernel mode the resulting action is always to stop the kernel. This is not necessarily the best solution since a retry of the failing instruction might succeed.

With CONFIG_SLAB_DEBUG=y networking over qeth doesn't work. The problem is that the qib structure embedded in the qeth_irq structure needs an alignment of 256 but kmalloc only guarantees an alignment of 8. When using SLAB debugging the alignment of qeth_irq is not sufficient for the embedded qib structure which causes all users of qdio (qeth and zfcp) to stop working. Allocate qeth_irq structure with __get_free_page. That wastes a small amount of memory (~2500 bytes) per online adapter. Signed-off-by:

The dasd state machine is not designed to enable an unformatted device, since 'unformatted' is a final state. The BIODASDENABLE ioctl calls dasd_enable_device() which never returns if the device is in this special state. Return -EPERM in dasd_increase_state for unformatted devices to make dasd_enable_device terminate. Note: To get such an unformatted device online it has to be re-analyzed. This means that the device needs to be disabled prior to re-enablement. Signed-off-by:

Avoid memory allocation with GFP_KERNEL in qdio_establish/qdio_shutdown. Use memory pool instead. (Otherwise this can lead to an I/O stall where qdio waits for a free page and zfcp waits for end of error recovery in low memory situations.) Signed-off-by:

If a signal handler has been established with the SA_ONSTACK option but no alternate stack is provided with sigaltstack(), the kernel still tries to install the alternate stack. Also when setting an alternate stack with sigalstack() and the SS_DISABLE flag, the kernel tries to install the alternate stack on signal delivery. Use the correct conditions sas_ss_flags() to check if the alternate stack has to be used. Signed-off-by:

Running abnormal VM splits causes weird problems - people can set non-standard splits by accident, then lots of time gets wasted diagnosing it - see the long "[stable] 2.6.16.6 breaks java... sort of" email thread. So we need to make this option harder to set. Use CONFIG_EMBEDDED for this. CONFIG_EMBEDDED isn't really the right thing to use, but there's nothing else obvious and avoiding these problems is more important than Kconfig purity. Signed-off-by:

CPU_HOTPLUG has race conditions when we use broadcast mode IPI. - First we introduced no_broadcast option (see include/asm-i386/mach-default/mach_ipi.h) - x86_64 solved it by using physical flat mode (same as bigsmp on i386) since this will not use broadcast shortcuts for IPI. - We switched to use bigsmp on i386 so that we can have same handling as x86_64, but apparently this caused an error message, if kernel was compiled without X86_GENERICARCH, X86_BIGSMP. The message "You have >8 CPUS..." which was bogus and misleading, and only indicated one of the above ARCH wasnt selected. So we do not switch to automatic bigsmp for HOTPLUG_CPU support in i386 until the other related config dependencies for SMP_SUSPEND etc can be done right.

Current address translation methods can produce wrong results, because virt_to_bus and vice versa may not produce correct offsets on dma-allocated memory. The right way is, while tracking both phys and virt address of the window that has been allocated for boffer descriptors, and use those numbers to compute the offset and make translation properly.
