Merge tag 'cputime-cleanups-for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks into sched/core
Pull cputime cleanups and optimizations from Frederic Weisbecker:
* Gather vtime headers that were a bit scattered around
* Separate irqtime and vtime namespaces that were
colliding, resulting in useless calls to irqtime accounting.
* Slightly optimize irq and guest vtime accounting.
