Subject: [GIT PULL] timers/nohz changes for v3.12

Linus,

Please pull the latest timers-nohz-for-linus git tree from:

   git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git timers-nohz-for-linus

   HEAD: c2e7fcf53c3cb02b4ada1c66a9bc8a4d97d58aba nohz: Include local CPU in full dynticks global kick

It mostly contains fixes and full dynticks off-case optimizations,
by Frederic Weisbecker.

NOTE: for some reason my pull request scripts failed to generate a proper 
diffstat so I've generated the shortlog and diffstat manually. All 
resulting mistakes are mine.

 Thanks,

	Ingo

      sched: Consolidate open coded preemptible() checks
      context_tracing: Fix guest accounting with native vtime
      vtime: Update a few comments
      context_tracking: Fix runtime CPU off-case
      nohz: Only enable context tracking on full dynticks CPUs
      context_tracking: Remove full dynticks' hacky dependency on wide context tracking
      context_tracking: Ground setup for static key use
      context_tracking: Optimize main APIs off case with static key
      context_tracking: Optimize guest APIs off case with static key
      context_tracking: Optimize context switch off case with static keys
      context_tracking: User/kernel broundary cross trace events
      vtime: Remove a few unneeded generic vtime state checks
      vtime: Fix racy cputime delta update
      context_tracking: Split low level state headers
      hardirq: Split preempt count mask definitions

      nohz: Rename a few state variables
      nohz: Optimize full dynticks state checks with static keys
      nohz: Optimize full dynticks's sched hooks with static keys
