Subject: [GIT PULL] cputime: Scaled cputime optimizations and cleanups
Date: Tue, 15 Nov 2016 03:06:48 +0100	[thread overview]
Message-ID: <1479175612-14718-1-git-send-email-fweisbec@gmail.com> (raw)

Ingo,

Please pull the sched/cputime branch that can be found at:

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

HEAD: bb953cdfa26c25e42beb748e7be71ea3d4927186

This set removes the dead arch and core code handling scaled cputime and
optimize the most common case where archs don't support scaled frequency
accounting.

Thanks,
	Frederic
