[PATCH tip/core/rcu 0/5] Miscellaneous fixes for 4.9

[Paul E. McKenney]

Hello!

This series contains miscellaneous fixes:

1.	Fix a soft lockup in the RCU's callback-offload (rcuo) kthreads,
	courtesy of Ding Tianhong.

2.	Use rcu_gp_kthread_wake() to wake up grace period kthreads,
	avoiding spurious/redundant wakeups, courtesy of Jisheng Zhang.

3.	Make wake_up_nohz_cpu() handle CPUs going offline.

4.	Don't use modular infrastructure in non-modular code, courtesy
	of Paul Gortmaker.

5.	Avoid redundant quiescent-state chasing by more carefully
	initializing flags for newly onlined CPUs.

							Thanx, Paul
