Ingo, Thomas,

timers/posix-timers-for-tip-v2
HEAD: 531f64fd6f46a3f2a3edb1b97ecc827c775932c5
This is the second version of the pull request that I sent you a few weeks ago:
http://lkml.kernel.org/r/1385221040-24731-1-git-send-email-fweis...@gmail.com
Changes in this v2:
* rebase against latest tip:timers/core (there was a conflict with some dynticks
patches)
* add a cleanup suggested by Kosaki in patch 02/10: remove a useless group
timer sample snapshot and rearm on timer rescheduling.
Also the previous pull request lacked a high level overall description, so I'm
adding one here.

Posix cpu timers changes for 3.14:
* Remove dying thread/process timers caching that were 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()
Thanks,
Frederic
