Ingo,
Please pull the latest cputime cleanups that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git tags/cputime-cleanups-for-mingo
for you to fetch changes up to 3e1df4f506836e6bea1ab61cf88c75c8b1840643:
cputime: Separate irqtime accounting from generic vtime (2012-10-29 21:31:32 +0100)
It is based on top of tip:sched/core of today.
Tested on x86 and powerpc. Built-tested only on ia64 and s390.
Thanks.
---------------------------------------------------------------- Cputime cleanups and optimizations:
* 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.
