2009-11-06md/raid5: make sure curr_sync_completes is uptodate when reshape startsNeilBrown
This value is visible through sysfs and is used by mdadm when it manages a reshape (backing up data that is about to be rearranged). So it is important that it is always correct. Current it does not get updated properly when a reshape starts which can cause problems when assembling an array that is in the middle of being reshaped. This is suitable for 2.6.31.y stable kernels.

2009-11-06md: don't clear endpoint for resync when resync is interrupted.NeilBrown
If a 'sync_max' has been set (via sysfs), it is wrong to clear it until a resync (or reshape or recovery ...) actually reached that point. So if a resync is interrupted (e.g. by device failure), leave 'resync_max' unchanged. This is particularly important for 'reshape' operations that do not change the size of the array. For such operations mdadm needs to monitor the reshape taking rolling backups of the section being reshaped. If resync_max gets cleared, the reshape can get ahead of mdadm and then the backups that mdadm creates are useless. This is suitable for 2.6.31.y stable kernels.

Annote acpi_processor_add with cpuinit since it calls a cpuinit function acpi_processor_power_init and fixes a section mismatch warning. We were warned by the following warning: LD drivers/acpi/processor.o WARNING: drivers/acpi/processor.o(.text+0x1829): Section mismatch in reference from the function acpi_processor_add() to the function .cpuinit.text:acpi_processor_power_init() The function acpi_processor_add() references the function __cpuinit acpi_processor_power_init().

Not a single line of actual code in the function was really fundamentally correct.

2009-11-04rtl8187: Fix kernel oops when device is removed when LEDS enabledLarry Finger
As reported by Rick Farina (sidhayn@gmail.com), removing the RTL8187 USB stick, or unloading the driver rtl8187 using rmmod will cause a kernel oops. There are at least two forms of the failure, (1) BUG: Scheduling while atomic, and (2) a fatal kernel page fault. This problem is reported in Bugzilla #14539. This problem does not occur for kernel 2.6.31, but does for 2.6.32-rc2, thus it is technically a regression; however, bisection did not locate any faulty patch. The fix was found by comparing the faulty code in rtl8187 with p54usb. My interpretation is that the handling of work queues in mac80211 changed enough to the LEDs to be unregistered before tasks on the work queues are cancelled. Previously, these actions could be done in either order. (Herton Ronaldo Krzesinski <herton@mandriva.com.br> reports that the code is the same in 2.6.31, so this may be a candidate for 2.6.31.x. -- JWL) Signed-off-by: Larry Finger <Larry.Finger@lwfinger.net> Reported-by: Rick Farina <sidhayn@gmail.com> Tested-by: Rick Farina <sidhayn@gmail.com> Cc: stable@kernel.org Signed-off-by: John W.

2009-11-04drm/radeon/kms: fix coherency issues on AGP cards.Dave Airlie
When we are evicting from VRAM->RAM we allocate the ttm object, but we don't set the caching policy on it before blitting into it. This means on AGP we end up blitting into cached pages, and the CPU later flushes out on top of them. This was mostly seen as font corruption. The other question is why we don't evict VRAM->GTT in a lot of cases, this would save us some cache transitions since a lot of objects that are evicted from VRAM will probably end up being pulled back in a few operations later, and evicting them to system memory involves 2 unnecessary cache transitions.
