Merge branch 'rcu/next' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu

Pull RCU updates from Paul E. McKenney:

	* Update RCU documentation.  These were posted to LKML at
	  https://lkml.org/lkml/2014/2/17/555.

	* Miscellaneous fixes.  These were posted to LKML at
	  https://lkml.org/lkml/2014/2/17/530.  Note that two of these
	  are RCU changes to other maintainer's trees: add1f0995454
	  (fs) and 8857563b819b (notifer), both of which substitute
	  rcu_access_pointer() for rcu_dereference_raw().

	* Real-time latency fixes.  These were posted to LKML at
	  https://lkml.org/lkml/2014/2/17/544.

	* Torture-test changes, including refactoring of rcutorture
	  and introduction of a vestigial locktorture.  These were posted
	  to LKML at https://lkml.org/lkml/2014/2/17/599.
