Merge branch 'for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Pull RCU updates from Paul E. McKenney: - Miscellaneous fixes, perhaps most notably removing obsolete code whose only purpose in life was to gather information for the now-removed RCU debugfs facility. Other notable changes include removing NO_HZ_FULL_ALL in favor of the nohz_full kernel boot parameter, minor optimizations for expedited grace periods, some added tracing, creating an RCU-specific workqueue using Tejun's new WQ_MEM_RECLAIM flag, and several cleanups to code and comments. - SRCU cleanups and optimizations. - Torture-test updates, perhaps most notably the adding of ARMv8 support, but also including numerous cleanups and usability fixes. Signed-off-by: Ingo Molnar <mingo@kernel.org>
