Merge branch 'for-mingo' of git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu into core/rcu
Pull RCU cleanup from Paul E. McKenney:
"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."
