[GIT PULL] perf updates

[Frederic Weisbecker]

There is an rfc patch in this set, so may be it's not that
pullable.

But for those who want to test or something, the set is in the
perf/core branch that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/random-tracing.git
	perf/core

Thanks,
	Frederic
