Subject: [PATCH tip/core/rcu 19/47] rcu: Streamline code produced by __rcu_read_unlock()

From: "Paul E. McKenney" <paulmck@...ux.vnet.ibm.com>

This is a port of commit #be0e1e21 to TINY_PREEMPT_RCU.  This uses
noinline to prevent rcu_read_unlock_special() from being inlined into
__rcu_read_unlock().
