Merge branch 'sched-idle-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Pull sched/idle changes from Ingo Molnar:
 "More idle code reorganization, to prepare for more integration.

  (Sent separately because it depended on pending timer work, which is
  now upstream)"

* 'sched-idle-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip:
  sched/idle: Add more comments to the code
  sched/idle: Move idle conditions in cpuidle_idle main function
  sched/idle: Reorganize the idle loop
  cpuidle/idle: Move the cpuidle_idle_call function to idle.c
  idle/cpuidle: Split cpuidle_idle_call main function into smaller functions
