Paul E. McKenney 66777e5821 rcu-tasks: Use context-switch hook for PREEMPT=y kernels 
Currently, the PREEMPT=y version of rcu_note_context_switch() does not
invoke rcu_tasks_qs(), and we need it to in order to keep RCU Tasks
Trace's IPIs down to a dull roar.  This commit therefore enables this
hook.
