Let people enable the advansys driver on x86-32, even though it's broken on other architectures due to missing DMA mapping infrastructure. It's used by Jeffrey Phillips Freeman <jeffreyfreeman@syncleus.com> and possibly others. Signed-off-by:Linus Torvalds <torvalds@osdl.org>

The FXSAVE information leak patch introduced a bug in FP exception handling: it clears FP exceptions only when there are already none outstanding. Mikael Pettersson reported that causes problems with the Erlang runtime and has tested this fix. 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. Add logic to retry the instruction if no more than 30 instruction processing damage checks occured in the last 5 minutes. Signed-off-by:

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.

If compiled into the kernel, parport_register_driver() is called before the parport driver has been initalised. This means that it is expected that tp_count is 0 after the parport_register_driver() call() - tipar's attach function will not be called until later during bootup. Signed-off-by:

There's an off-by-1 in kernel/power/main.c:state_store() ... if your kernel just happens to have some non-zero data at pm_states[PM_SUSPEND_MAX] (i.e. one past the end of the array) then it'll let you write anything you want to /sys/power/state and in response the box will enter S5. Signed-off-by:

In SLES10 (2.6.16) crash dumping (in my experience, LKCD) is unable to capture the second page of the 2-page task/stack allocation. This is particularly troublesome for dump analysis, as the stack traceback cannot be done. (A similar convention is probably needed throughout the kernel to make kernel multi-page allocations detectable for dumping) Multi-page kernel allocations are represented by the single page structure associated with the first page of the allocation. The page structures associated with the other pages are unintialized. If the dumper is selecting only kernel pages it has no way to identify any but the first page of the allocation. The fix is to make the task/stack allocation a compound page. Signed-off-by:

MPI programs using certain debug options have a long startup time. This was traced to a "vmalloc/vfree" in the code that reads /proc/sgi_sn/sn_topology. On large systems, vfree requires an IPI to all cpus to do TLB purging. Replace the vmalloc/vfree with kmalloc/kfree. Although the size of the structure being allocated is unknown, it will not not exceed 96 bytes. Signed-off-by:
