Subject: [PATCH tip/core/rcu 0/16] Expedited grace-period changes for 4.7

Hello!

This series contains updates for RCU's expedited grace-period facility:

1.	Make expedited RCU-sched grace period immediately detect idle.

2.	Make expedited RCU-preempt stall warnings count accurately.

3.	Make cond_resched_rcu_qs() supply RCU-sched expedited QS.

4.	Fix synchronize_rcu_expedited() header comment.

5.	Add event tracing definitions for expedited grace periods.

6.	Add funnel-locking tracing for expedited grace periods.

7.	Add expedited-grace-period event tracing.

8.	Remove expedited GP funnel-lock bypass.

9.	Force boolean subscript for expedited stall warnings.

10.	Shorten expedited_workdone* to exp_workdone*.

11.	Enforce expedited-GP fairness via funnel wait queue.

12.	Add exp_funnel_lock() fastpath for new funnel wait queue.

13.	Consolidate expedited GP code into rcu_exp_wait_wake().

14.	Consolidate expedited GP tracing into rcu_exp_gp_seq_snap().

15.	Consolidate expedited GP code into exp_funnel_lock().

16.	Overlap wakeups with next expedited grace period.

							Thanx, Paul
