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" * 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (37 commits) rcu: Create RCU-specific workqueues with rescuers torture: Provide more sensible nreader/nwriter defaults for rcuperf torture: Grace periods do not piggyback off of themselves torture: Adjust rcuperf trace processing to allow for workqueues torture: Default jitter off when running rcuperf torture: Specify qemu memory size with --memory argument rcutorture: Add basic ARM64 support to run scripts rcutorture: Update kvm.sh header comment rcutorture: Record which grace-period primitives are tested rcutorture: Re-enable testing of dynamic expediting rcutorture: Avoid fake-writer use of undefined primitives rcutorture: Abstract function and module names rcutorture: Replace multi-instance kzalloc() with kcalloc() rcu: Remove SRCU throttling srcu: Remove dead code in srcu_gp_end() srcu: Reduce scans of srcu_data in counter wrap check srcu: Prevent sdp->srcu_gp_seq_needed_exp counter wrap srcu: Abstract function name rcu: Make expedited RCU CPU selection avoid unnecessary stores rcu: Trace expedited GP delays due to transitioning CPUs ...
