Merge branch 'timers/posix-timers-for-tip-v2' of git://git./linux/kernel/git/frederic/linux-dynticks into timers/core

Pull posix cpu timer changes for v3.14 from Frederic Weisbecker:

 * Remove dying thread/process timers caching that was complicating the code
   for no significant win.

 * Remove early task reference release on dying timer sample read. Again it was
   not worth the code complication. The other timer's resources aren't released
   until timer_delete() is called anyway (or when the whole process dies).

 * Remove leftover arguments in reaped target cleanup

 * Consolidate some timer sampling code

 * Remove use of tasklist lock

 * Robustify sighand locking against exec and exit by using the safer
   lock_task_sighand() API instead of sighand raw locking.

 * Convert some unnecessary BUG_ON() to WARN_ON()
