Pull scheduler fixes from Ingo Molnar:
 "Misc deadline scheduler fixes, mainly for a new category of bugs that
  were discovered and fixed recently:

   - Fix a race condition in the DL server

   - Fix a DL server bug which can result in incorrectly going idle when
     there's work available

   - Fix DL server bug which triggers a WARN() due to broken
     get_prio_dl() logic and subsequent misbehavior

   - Fix double update_rq_clock() calls

   - Fix setscheduler() assumption about static priorities

   - Make sure balancing callbacks are always called

   - Plus a handful of preparatory commits for the fixes"
