Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU updates from Ingo Molnar:
"The main RCU subsystem changes in this cycle were:
- 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"
