For the rcutorture component:

Acked-by: Paul E. McKenney <paulmck@xxxxxxxxxxxxxxxxxx>
Tested-by: Paul E. McKenney <paulmck@xxxxxxxxxxxxxxxxxx>

Given that this portion of the patch is self-sufficient, I have queued
the rcutorture portion of this patch with your signed-off-by, which I
can push for either 3.3 or 3.4 (default is most likely 3.4).  Of course,
if you would prefer some other approach, please let me know.

							Thanx, Paul
