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 changes in this cycle are: - the combination of tree geometry-initialization simplifications and OS-jitter-reduction changes to expedited grace periods. These two are stacked due to the large number of conflicts that would otherwise result. - privatize smp_mb__after_unlock_lock(). This commit moves the definition of smp_mb__after_unlock_lock() to kernel/rcu/tree.h, in recognition of the fact that RCU is the only thing using this, that nothing else is likely to use it, and that it is likely to go away completely. - documentation updates. - torture-test updates. - misc fixes" * 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (60 commits) rcu,locking: Privatize smp_mb__after_unlock_lock() rcu: Silence lockdep false positive for expedited grace periods rcu: Don't disable CPU hotplug during OOM notifiers scripts: Make checkpatch.pl warn on expedited RCU grace periods rcu: Update MAINTAINERS entry rcu: Clarify CONFIG_RCU_EQS_DEBUG help text rcu: Fix backwards RCU_LOCKDEP_WARN() in synchronize_rcu_tasks() rcu: Rename rcu_lockdep_assert() to RCU_LOCKDEP_WARN() rcu: Make rcu_is_watching() really notrace cpu: Wait for RCU grace periods concurrently rcu: Create a synchronize_rcu_mult() rcu: Fix obsolete priority-boosting comment rcu: Use WRITE_ONCE in RCU_INIT_POINTER rcu: Hide RCU_NOCB_CPU behind RCU_EXPERT rcu: Add RCU-sched flavors of get-state and cond-sync rcu: Add fastpath bypassing funnel locking rcu: Rename RCU_GP_DONE_FQS to RCU_GP_DOING_FQS rcu: Pull out wait_event*() condition into helper function documentation: Describe new expedited stall warnings rcu: Add stall warnings to synchronize_sched_expedited() ...
