[PATCH 0/6] timers nohz updates preview for 3.11

[Frederic Weisbecker <fweisbec@gmail.com>]

Hi,

So here is a first batch of some patches I think could go for 3.11
Except for "rcu: Prevent CPU from stopping tick if awaited for quiescent state report"
which needs more thinking. I believe we can do more from the IPI to force a
quiescent state without the need to restart the tick.

For those who want to check through git:

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

Thanks,
	Frederic
