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().

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
