[PATCH RFC tip/core/rcu 0/8] Waketorture, not for inclusion

[Paul E. McKenney]

Hello!

And for your amusement, this series provides a waketorture module.  It is
intended to increase the probability of a heisenbug or three I have been
chasing for longer than I care to admit.  Should it someday actually
significantly increase that probability, I might consider submitting it
for acceptance.  In the meantime, for your amusement:

1.	Add a wakeup-torture module.

2.	Update scripting to accommodate waketorture.

3.	Don't kick kthreads unless grace period or request.

4.	Add utilization measurement.

5.	Add hrtimer support for fine-grained event scheduling.

6.	Make waketorture always hotplug the same CPU.

7.	Make waketorture kill test if no hotpluggable CPUs.

8.	Affinity waiter tasks away from hotpluggable CPU.

							Thanx, Paul
