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.
14. Add lockless list traversal primitives, courtesy of
Alexey Kardashevskiy.
Changes since v1:
o Add commit 14, the lockless traversal primitives.
o Wire up to correct cover letter. :-/
Thanx, Paul
