Subject: [GIT PULL] cputime fixes and cleanups

Ingo,

Please pull the sched/cputime branch that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	sched/cputime

It is based on top of tip:sched/core due to conflicts against commits in
this branch.

HEAD: 363e4ca0466a3db318fce18e53f6e492bffc0202

---
Summary of changes:

* Fix system/idle cputime leaked on cputime accounting (all nohz configs)
* Remove nohz full messy ad-hoc irqtime accounting, make it compatible
  with CONFIG_IRQ_TIME_ACCOUNTING instead.
* Cleanups
* Remove unecessary irq disablement on irqtime code.

Thanks,
	Frederic
