[PATCH rcu 08/16] rcu/sync: Use call_rcu_hurry() instead of call_rcu

[Paul E. McKenney]

From: "Joel Fernandes (Google)" <joel@xxxxxxxxxxxxxxxxx>

call_rcu() changes to save power will slow down rcu sync. Use the
call_rcu_hurry() API instead which reverts to the old behavior.

[ paulmck: Apply s/call_rcu_flush/call_rcu_hurry/ feedback from Tejun Heo. ]
