| * sched: Fix/clarify set_task_cpu() locking rulesPeter Zijlstra2011-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sergey reported a CONFIG_PROVE_RCU warning in push_rt_task where set_task_cpu() was called with both relevant rq->locks held, which should be sufficient for running tasks since holding its rq->lock will serialize against sched_move_task(). Update the comments and fix the task_group() lockdep test.

| * lockdep: Fix lock_is_held() on recursionPeter Zijlstra2011-06-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The main lock_is_held() user is lockdep_assert_held(), avoid false assertions in lockdep_off() sections by unconditionally reporting the lock is taken. [ the reason this is important is a lockdep_assert_held() in ttwu() which triggers a warning under lockdep_off() as in printk() which can trigger another wakeup and lock up due to spinlock recursion, as reported and heroically debugged by Arne Jansen ] Reported-and-tested-by: Arne Jansen <lists@die-jansens.de> Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: <stable@kernel.org> Link: http://lkml.kernel.org/r/1307398759.2497.966.camel@laptop Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * sched: Fix schedstat.nr_wakeups_migratePeter Zijlstra2011-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | While looking over the code I found that with the ttwu rework the nr_wakeups_migrate test broke since we now switch cpus prior to calling ttwu_stat(), hence the test is always true. Cure this by passing the migration state in wake_flags. Also move the whole test under CONFIG_SMP, its hard to migrate tasks on UP :-) Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/n/tip-pwwxl7gdqs5676f1d4cx6pj7@git.kernel.org Signed-off-by: Ingo Molnar <mingo@elte.hu>
| * sched: Fix cross-cpu clock sync on remote wakeupsPeter Zijlstra2011-05-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Markus reported that commit 317f394160e ("sched: Move the second half of ttwu() to the remote cpu") caused some accounting funnies on his AMD Phenom II X4, such as weird 'top' results. It turns out that this is due to non-synced TSC and the queued remote wakeups stopped coupeling the two relevant cpu clocks, which leads to wakeups seeing time jumps, which in turn lead to skewed runtime stats. Add an explicit call to sched_clock_cpu() to couple the per-cpu clocks to restore the normal flow of time.

Note that g4x_compute_wm0 takes a 'plane' argument while ironlake_compute_wm0 took a 'pipe' argument. Both should have used a 'plane' argument, so this patch fixes that as well (not that it caused a problem; ironlake always uses pipe == plane).

Though we need the mask set even on UP to avoid a horrible ifdeffery especially in the broadcast code. For SMP we can at least try to survive with a warning and set the cpumask of the cpu we're running on. That gives a decent chance to bring the machine up and retrieve the debug info.

Previously, 85722cda changed the ordering to ensure that the mmu_lock was initialized before mmu notifier registration, but there is still a race where the mmu notifier could come in and try accessing other portions of struct kvm before they are intialized. Solve this by moving the mmu notifier registration to occur after the structure is completely initialized.

It failed to copy the port value from RDX register for string and "in,out ax,dx" instructions. Fix it by reading RDX register at decode stage when appropriate. Fixes FC8.32 installation.

David had a huge impact on our community, both personally in the lives of the people he worked with, and technically in the design and maintenance of several subsystems. He is greatly missed. He also leaves behind a number of much loved subsystems now orphaned. This patch updates the MAINTAINERS file for the areas that David was responsible for and adds an entry for him to the CREDITS file.
