2012-05-22drm: Delete the vblank timer synchronously at cleanup timeLaurent Pinchart
A race condition exists in drm_vblank_cleanup() if the vblank disable timer callback runs after freeing the memory that its callback function tries to access. Fix this by deleting the timer synchronously.

2012-05-22drm/dp: Add DPCD defines for register 0x007Adam Jackson
Low four bits are downstream port count. High bit indicates peer OUI support. OUI matching will allow us to do additional per-sink handling for things like DP->VGA bandwidth limits or (hopefully) the iMac-as- display hack.

2012-05-22gma500: handle poulsbo cursor restrictionPatrik Jakobsson
Poulsbo needs a physical address in the cursor base register. We allocate a stolen memory buffer and copy the cursor image provided by userspace into it. When/If we get our own userspace driver we can map this stolen memory directly. The patch also adds a mark in chip ops so we can identify devices that has this requirement.

2012-05-22powerpc: Fix irq distributionKim Phillips
setting CONFIG_IRQ_ALL_CPUS distributes IRQs to CPUs only when the number of online CPUs equals NR_CPUS. See commit 280ff97494e0fef4124bee5c52e39b23a18dd283 "sparc64: fix and optimize irq distribution" for more details. Using the online mask fixes IRQ-to-CPU distribution on systems that boot with less than NR_CPUS.

2012-05-22ktest: Add useful example configsSteven Rostedt
I've been asked several times to provide more useful example configs for ktest.pl, as the sample.conf is too complex (because it explains all configs).

2012-05-22ktest: Add USE_OUTPUT_MIN_CONFIG to avoid prompt on make_min_configSteven Rostedt
If the file that OUTPUT_MIN_CONFIG exists then ktest.pl will prompt the user and ask them if the OUTPUT_MIN_CONFIG should be used as the starting point for make_min_config instead of MIN_CONFIG. This is usually the case, and to allow the user to do so, which is helpful if the user is creating different min configs based on tests, and they know one is a superset of another test, they can set USE_OUTPUT_MIN_CONFIG to one, which will prevent kest.pl from prompting to use the OUTPUT_MIN_CONFIG and it will just use it. If USE_OUTPUT_MIN_CONIFG is set to zero, then ktest.pl will continue to use MIN_CONFIG instead. The default is that USE_OUTPUT_MIN_CONFIG is undefined.

2012-05-21score: add handling of NOTIFY_RESUME to do_notify_resume()Al Viro
It's already called if TIF_NOTIFY_RESUME is set, so we only need to add the actual work. Note that checking for RESTORE_SIGMASK was not needed - set_restore_sigmask() also sets SIGPENDING, so we never RESTORE_SIGMASK without SIGPENDING. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2012-05-21m68k: add TIF_NOTIFY_RESUME and handle it.Al Viro
TIF_NOTIFY_RESUME added (as bit 5). That way nommu glue needs no changes at all; mmu one needs just to replace jmi do_signal_return to jne do_signal_return There we have flags shifted up, until bit 6 (SIGPENDING) is in MSBit; instead of checking that MSBit is set (jmi) we check that MSBit or something below it is set (jne); bits 0..4 are never set, so that's precisely "bit 6 or bit 5 is set". Usual handling of NOTIFY_RESUME/SIGPENDING is done in do_notify_resume(); glue calls it instead of do_signal(). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
