Hello!

This series contains miscellaneous fixes:

1.	Use hlist_nulls_next_rcu() in hlist_nulls_add_tail_rcu(),
	courtesy of Zhao Mengmeng.

2.	Consolidate initialization and CPU-hotplug code.

3.	Throttle callback invocation based on number of ready callbacks.

4.	Upgrade header comment for poll_state_synchronize_rcu().

5.	Make RCU_LOCKDEP_WARN() avoid early lockdep checks.

6.	Suppress smp_processor_id() complaint in
	synchronize_rcu_expedited_wait().

7.	Make rcu_blocking_is_gp() stop early-boot might_sleep(), courtesy
	of Zqiang.

8.	Test synchronous RCU grace periods at the end of rcu_init().

9.	Allow expedited RCU CPU stall warnings to dump task stacks.

10.	Remove redundant call to rcu_boost_kthread_setaffinity(),
	courtesy of Zqiang.

						Thanx, Paul
