Hello!

This series contains miscellaneous fixes:

1.	Report callbacks enqueued on offline CPU blind spot, courtesy
	of Frederic Weisbecker.

2.	Make rcu_report_exp_cpu_mult() caller acquire lock.

3.	Move rcu_report_exp_rdp() setting of ->cpu_no_qs.b.exp under lock.

4.	Replace open-coded rcu_exp_need_qs() from rcu_exp_handler()
	with call.

5.	Make preemptible rcu_exp_handler() check idempotency.

6.	Add KCSAN exclusive-writer assertions for rdp->cpu_no_qs.b.exp.

7.	Add lockdep_assert_irqs_disabled() to rcu_exp_need_qs().

8.	MAINTAINERS: Update RCU git tree.

						Thanx, Paul
