Merge branch 'for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Pull RCU and LKMM changes from Paul E. McKenney: - Documentation updates. - Miscellaneous fixes. - Dynamic tick (nohz) updates, perhaps most notably changes to force the tick on when needed due to lengthy in-kernel execution on CPUs on which RCU is waiting. - Replace rcu_swap_protected() with rcu_prepace_pointer(). - Torture-test updates. - Linux-kernel memory consistency model updates.
