[PATCH tip/core/rcu 0/16] Miscellaneous fixes for 4.3

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

Hello!

This series contains miscellaneous fixes.

1.	Drop RCU_USER_QS in favor of NO_HZ_FULL.

2.	Deinline rcu_read_lock_sched_held() even in kernels built with
	CONFIG_DEBUG_LOCK_ALLOC=y, courtesy of Denys Vlasenko.

3.	Change srcu_readers_active()'s return type to bool, courtesy
	of Nicholas Mc Guire.

4.	Add RCU-sched flavors get-state/cond-sync functions, namely
	get_state_synchronize_sched() and cond_synchronize_sched().

5.	Hide RCU_NOCB_CPU behind RCU_EXPERT, arriving at fully
	automated Kconfig setup for RCU.

6.	Use WRITE_ONCE in RCU_INIT_POINTER, courtesy of Peter Zijlstra.

7.	Fix obsolete priority-boosting comment.

8.	Create a synchronize_rcu_mult() to allow overlapped synchronous
	grace periods.

9.	Use synchronize_rcu_mult() to make _cpu_down() wait for its
	RCU and RCU-sched grace periods concurrently.

10.	Make rcu_is_watching() really be notrace, courtesy of =
	Alexei Starovoitov.

11.	Rename rcu_lockdep_assert() to RCU_LOCKDEP_WARN().

12.	Fix backwards RCU_LOCKDEP_WARN() in synchronize_rcu_tasks().

13.	Clarify CONFIG_RCU_EQS_DEBUG help text.

14.	Update RCU MAINTAINERS email address, courtesy of Lai Jiangshan.

15.	Make checkpatch.pl warn on expedited RCU grace periods.

16.	Don't disable CPU hotplug during OOM notifiers.

							Thanx, Paul
