Paul E. McKenney 1f3e5f51b9 rcu: Add RCU-preempt check for waiting on newly onlined CPU 
RCU should only be waiting on CPUs that were online at the time that the
current grace period started.  Failure to abide by this rule can result
in confusing splats during grace-period cleanup and initialization.
This commit therefore adds a check to RCU-preempt's preempted-task
queuing that checks for waiting on newly onlined CPUs.
