[GIT PULL rcu/next] Additional RCU commit for 4.3

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

Hello, Ingo,

This additional series contains a single change:

1.	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.

This change has been subjected to 0day Test Robot and -next testing,
and is available in the git repository at:

  git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git for-mingo
