Subject: [GIT PULL] sched: Cputime update for 3.10

Ingo,

Please pull the latest cputime accounting updates that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	sched/core

HEAD: d9a3c9823a2e6a543eb7807fb3d15d8233817ec5

Some users are complaining that their threadgroup's runtime accounting freezes
after a week or so of intense cpu-bound workload. This set tries to fix the issue
by reducing the risk of multiplication overflow in the cputime scaling code.

Thanks.
