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.
