rcu: Get rid of synchronize_sched_expedited()'s polling loop
This commit gets rid of synchronize_sched_expedited()'s mutex_trylock() polling loop in favor of a funnel-locking scheme based on the rcu_node tree. The work-done check is done at each level of the tree, allowing high-contention situations to be resolved quickly with reasonable levels of mutex contention. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
