Subject: [GIT PULL] nohz updates for 3.18

Ingo,

Please pull the nohz/fixes-v3 branch that can be found at:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	nohz/fixes-v3

HEAD: 9b01f5bf3999a3db5b1bbd9fdfd80d8d304e94ee

---
Changes summary:

* Fix crash resulting from nohz kick irq work when called from the tick.
This callback expect to be handled on irq work own interrupt otherwise
we run into a deadlock.

* Enforce nohz_full to depend on arch to support irq work interrupts.
Without that support, irq work run from the tick but the tick can be
shutdown on nohz full.

* Nohz init code consolidation

Thanks,
	Frederic
