Subject[GIT PULL] cputime: Cleanups and optimizations
Date
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.

Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com>

----------------------------------------------------------------
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
