[PATCH tip/core/rcu 0/5] Idle changes for 3.8

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

Hello!

This patch series contains changes to RCU's interaction with idle.
The individual patches are as follows:

1.	Remove a layer of indirection to rcu_user_hooks_switch().
	(Courtesy of Frederic Weisbecker.)
2.	Update RCU_FAST_NO_HZ help text to remove the warning about
	running on large systems.
3.	Add "rcu_expedited" boot and sysfs parameters that cause the
	kernel to substitute expedited primitives for the normal
	grace period primitives.  (Courtesy of Antti P Miettinen.)
4.	Fix a precedence error in cpu_needs_another_gp() that
	surprisingly had no effect -- but clarity is good.
5.	Fix grammar issue in RCU_USER_QS help text.  (Courtesy of
	Paul Gortmaker.)

							Thanx, Paul
