Subject: [PATCH tip/core/rcu 0/18] Miscellaneous fixes for v5.2

Hello!

This series contains miscellaneous fixes.

	real-time guys have disabled expediting altogether, that is).

2.	Avoid unnecessary softirq when system is idle, courtesy of
	Joel Fernandes.

3.	rcu_qs -- Use raise_softirq_irqoff to not save irqs twice,
	courtesy of Cyrill Gorcunov.

4.	Make exit_rcu() handle non-preempted RCU readers.

5.	Set rcutree.kthread_prio sysfs access to read-only, courtesy
	of Liu Song.

6.	MAINTAINERS: RCU now has its own email list.

7.	MAINTAINERS: Add -rcu branch name ("dev").

8.	rcu: Move common code out of if-else block, courtesy of Akira
	Yokosawa.

9.	Allow rcu_nocbs= to specify all CPUs.

10.	Report error for bad rcu_nocbs= parameter values.

11.	Fix self-wakeups for grace-period kthread, courtesy of Neeraj
	Upadhyay.

12.	Default jiffies_to_sched_qs to jiffies_till_sched_qs, courtesy
	of Neeraj Upadhyay.

13.	Do a single rhp->func read in rcu_head_after_call_rcu(),
	courtesy of Neeraj Upadhyay.

14.	Update jiffies_to_sched_qs and adjust_jiffies_till_sched_qs()
	comments.

15.	Fix force_qs_rnp() header comment, courtesy of Zhouyi Zhou.

16.	Eliminate redundant NULL-pointer check.
