[PATCH tip/core/rcu 0/6] Fixes for 3.8

[Paul E. McKenney]

Hello!

This patch contains fixes as follows:

1.	Reinstate a grace-period acceleration that permits invoking
	the first callback registered on an idle system in one grace
	period rather than two.  The previous version of this acceleration
	was invalidated by the new grace-period kthreads.
2.	Fix an integer-size mismatch that prevented RCU from shifting
	to bulk-callback-invocation mode under overload.  (Courtesy of
	Eric Dumazet.)
3.	Remove list_for_each_continue_rcu(), as it is no longer used.
4.	Update rcutorture's module-parameter printout to include new
	parameters.
5.	Document the memory-ordering properties of RCU's grace-period
	primitives.  Note that the SRCU rewrite weakened these properties
	slightly.
6.	Reduce the RCU CPU stall warning timeout to 21 seconds so that
	it is once again somewhat shorter than the soft-lockup timeout.

							Thanx, Paul
