Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU updates from Ingo Molnar: "Main RCU changes this cycle were: - Full-system idle detection. This is for use by Frederic Weisbecker's adaptive-ticks mechanism. Its purpose is to allow the timekeeping CPU to shut off its tick when all other CPUs are idle. - Miscellaneous fixes. - Improved rcutorture test coverage. - Updated RCU documentation" * 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (30 commits) nohz_full: Force RCU's grace-period kthreads onto timekeeping CPU nohz_full: Add full-system-idle state machine jiffies: Avoid undefined behavior from signed overflow rcu: Simplify _rcu_barrier() processing rcu: Make rcutorture emit online failures if verbose rcu: Remove unused variable from rcu_torture_writer() rcu: Sort rcutorture module parameters rcu: Increase rcutorture test coverage rcu: Add duplicate-callback tests to rcutorture doc: Fix memory-barrier control-dependency example rcu: Update RTFP documentation nohz_full: Add full-system-idle arguments to API nohz_full: Add full-system idle states and variables nohz_full: Add per-CPU idle-state tracking nohz_full: Add rcu_dyntick data for scalable detection of all-idle state nohz_full: Add Kconfig parameter for scalable detection of all-idle state nohz_full: Add testing information to documentation rcu: Eliminate unused APIs intended for adaptive ticks rcu: Select IRQ_WORK from TREE_PREEMPT_RCU rculist: list_first_or_null_rcu() should use list_entry_rcu() ...
