Subject: [PATCH tip/core/rcu 0/6] Idle entry/exit changes for 3.13

Hello!

This series updates RCU's idle entry/exit processing:

1.	Remove redundant code from rcu_cleanup_after_idle().

2.	Throttle rcu_try_advance_all_cbs() execution to avoid kbuild
	slowdowns.

3.	Throttle non-lazy-callback-induced invoke_rcu_core() invocations.

4.	Add primitive to determine whether it is safe to enter an RCU
	read-side critical section.

5.	Upgrade EXPORT_SYMBOL() to EXPORT_SYMBOL_GPL().

6.	Change rcu_is_cpu_idle() function to __rcu_is_watching() for
	naming consistency.

							Thanx, Paul
