Subject: [PATCH 0/8] perf: Finer grained full dynticks handling 

Hi,

This patchset inspires from Peterz patch in http://marc.info/?l=linux-kernel&m=137155182121860
to make perf retain the timer tick less often, ie: only when there are freq events
or when one throttles.

The main purpose is to make the lockup detector work with full dynticks, as I suspect
that distros want to enable both...


You can fetch from:

Thanks,
	Frederic
