Subject: [PATCH] rcu: Eliminate local variable signaled from
 force_quiescent_state()

Because the root rcu_node lock is held across entry to the
switch statement in force_quiescent_state(), it is no longer
necessary to snapshot rsp->signaled to a local variable.
Eliminate both the snapshotting and the local variable.
