Merge branch 'rcu/next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Pull the v3.18 RCU changes from Paul E. McKenney:
"
* Update RCU documentation. These were posted to LKML at
https://lkml.org/lkml/2014/8/28/378.
* Miscellaneous fixes. These were posted to LKML at
https://lkml.org/lkml/2014/8/28/386. An additional fix that
eliminates a documented (but now inconvenient) deadlock between
RCU hotplug and expedited grace periods was posted at
https://lkml.org/lkml/2014/8/28/573.
* Changes related to No-CBs CPUs and NO_HZ_FULL. These were posted
to LKML at https://lkml.org/lkml/2014/8/28/412.
* Torture-test updates. These were posted to LKML at
https://lkml.org/lkml/2014/8/28/546 and at
https://lkml.org/lkml/2014/9/11/1114.
* RCU-tasks implementation. These were posted to LKML at
https://lkml.org/lkml/2014/8/28/540.
