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. " Signed-off-by: Ingo Molnar <mingo@kernel.org>
