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.

Frederic Weisbecker (5):
vtime: Gather vtime declarations to their own header file
vtime: Make vtime_account_system() irqsafe
kvm: Directly account vtime to system on guest switch
cputime: Specialize irq vtime hooks
cputime: Separate irqtime accounting from generic vtime
