[PATCH tip/core/rcu 0/13] Miscellaneous fixes for 4.5

[Paul E. McKenney]

Hello!

This series contains miscellaneous fixes for 4.5:

1.	Move lock_class_key to local scope within rcu_init_one().

2.	Make rcu/tree_trace.c explicitly non-modular, courtesy of
	Paul Gortmaker.

3.	Save a line of code by streamlining rcu_sched_qs() control flow.

4.	Remove lock-acquisition loop from rcu_read_unlock_special(),
	but leave WARN_ON_ONCE().

5.	Fix obsolete rcu_bootup_announce_oddness() comment.

6.	Avoid tick_nohz_active checks on NOCBs CPUs, thus reducing
	to/from-idle latency.

7.	Stop disabling interrupts in scheduler fastpaths.

8.	Eliminate unused rcu_init_one() "rda" argument.

9.	Make cpu_needs_another_gp() be bool.

10.	Don't redundantly disable irqs in rcu_irq_{enter,exit}(),
	thus improving interrupt latency slightly.

11.	Fix comment for rcu_dereference_raw_notrace(), courtesy of
	Alexey Kardashevskiy.

12.	Move wakeup out from under rnp->lock, courtesy of Peter Zijlstra.

13.	Make rcu_gp_init() be bool.

							Thanx, Paul
