[PATCH 0/9] nohz: Tick dependency mask v5

From: Frederic Weisbecker
Date: Thu Feb 04 2016 - 12:01:30 EST


Few changes in this version.
It is mostly about off-case optimizations using static keys:

* Use wrappers named tick_[set,clear]_dep on top of
tick_nohz_[set,clear]_dep in order to optimize off-cases using static
keys.

* Add Chris's reviewed-by

* Rebase against v4.5-rc1
