Subject[PATCH tip/core/rcu 12/12] rcu: Remove unused stop-machine #include
Date
From: "Paul E. McKenney" <paulmck@kernel.org>

Long ago, RCU used the stop-machine mechanism to implement expedited
grace periods, but no longer does so. This commit therefore removes
the no-longer-needed #includes of linux/stop_machine.h.
