Merge branch 'timers/posix-timers-for-tip-v2' of git://git.kernel.org/pub/scm/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()
