This patch set provides a couple of additional grace-period-processing
cleanups:

1.	Propagate ->completed through the rcu_node hierarchy
	when RCU goes idle to prevent an additional needless
	grace period from being started.

2.	Make force_quiescent_state() take a snapshot of ->gpnum-1
	rather than ->completed for consistency with rcu_sched_qs()
	and friends.
