[PATCH tip/core/rcu 0/12] Miscellaneous fixes for v4.1

["Paul E. McKenney" <paulmck@linux.vnet.ibm.com>]

Hello!

This series contains miscellaneous fixes:

1.	Merge identical definitions of the rcu_synchronize structure
	and the wakeme_after_rcu() functions.

2.	Avoid needlessly writing to rnp->completed when a new grace
	period is started, courtesy of Lai Jiangshan.

3.	Fix a couple of typos in rcu_all_qs() comment header.

4.	Eliminate CONFIG_PROVE_RCU as a separately settable Kconfig
	parameter by driving its value off of CONFIG_PROVE_LOCKING.

5.	Remove a #ifdef from tree.c by moving the rcu_init_levelspread()
	functions to tree_plugin.h.  Only moves code.

6.	Improve diagnostics for blocked critical sections in interrupt
	handlers.

7.	Use IS_ENABLED() to simplify rcu_bootup_announce_oddness().

8.	Add rcu_bootup_announce_oddness() check for non-default
	CONFIG_RCU_FANOUT_LEAF values.

9.	Reverse rcu_dereference_check() conditions to avoid invoking
	lockdep functions from NMI handlers.

10.	Avoid script syntax error when insufficient CPUs.

11.	Put rcu_sched_force_quiescent_state() back where it belongs.
	Only code movement.

12.	Remove redundant check of cpu_online() by __call_rcu_core(),
	courtesy of Yao Dongdong.

							Thanx, Paul
