* 'sched-fixes-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip: sched, trace: Fix sched_switch() prev_state argument sched: Fix wake_affine() vs RT tasks sched: Make sure timers have migrated before killing the migration_thread
For CONFIG_PREEMPT=y kernels the sched_switch(.prev_state) argument isn't useful because we can get preempted with current->state != TASK_RUNNING without actually getting removed from the runqueue. Cure this by treating all preempted tasks as runnable from the tracer's point of view.

tracepoint_probe_unregister() does not synchronize against the probe callbacks, so do that explicitly. This properly serializes the callbacks and the free of the data used therein. Also, use this_cpu_ptr() where possible.

Fixed up trivial conflict in fs/ext4/fsync.c
The TRACE_EVENT() macros automate creation of trace events. To automate initialization, the set up variables are loaded in a special section that is read on boot up. GCC is not aware that these static variables are used and will complain about them if we do not inform GCC that they are indeed used. One of the declarations of the event element was missing a __used annotation. This patch adds it. Reported-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
