Merge branch 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull RCU updates from Ingo Molnar: - updates to the handling of expedited grace periods - updates to reduce lock contention in the rcu_node combining tree [ These are in preparation for the consolidation of RCU-bh, RCU-preempt, and RCU-sched into a single flavor, which was requested by Linus in response to a security flaw whose root cause included confusion between the multiple flavors of RCU ] - torture-test updates that save their users some time and effort - miscellaneous fixes * 'core-rcu-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (44 commits) rcu/x86: Provide early rcu_cpu_starting() callback torture: Make kvm-find-errors.sh find build warnings rcutorture: Abbreviate kvm.sh summary lines rcutorture: Print end-of-test state in kvm.sh summary rcutorture: Print end-of-test state torture: Fold parse-torture.sh into parse-console.sh torture: Add a script to edit output from failed runs rcu: Update list of rcu_future_grace_period() trace events rcu: Drop early GP request check from rcu_gp_kthread() rcu: Simplify and inline cpu_needs_another_gp() rcu: The rcu_gp_cleanup() function does not need cpu_needs_another_gp() rcu: Make rcu_start_this_gp() check for out-of-range requests rcu: Add funnel locking to rcu_start_this_gp() rcu: Make rcu_start_future_gp() caller select grace period rcu: Inline rcu_start_gp_advanced() into rcu_start_future_gp() rcu: Clear request other than RCU_GP_FLAG_INIT at GP end rcu: Cleanup, don't put ->completed into an int rcu: Switch __rcu_process_callbacks() to rcu_accelerate_cbs() rcu: Avoid __call_rcu_core() root rcu_node ->lock acquisition rcu: Make rcu_migrate_callbacks wake GP kthread when needed ...
