Subject: [PATCH tip/core/rcu 0/2] Expedited grace-period changes for v4.19

Hello!

This series contains a couple of changes to RCU expedited grace periods:

1.	Initialize the last rcu_node structure via direct call rather than
	via workqueue.

2.	Make parallel initialization of parallel grace periods handle the
	possibility of CPU 0 begin offline, courtesy of Boqun Feng.
	(This is currently marked Not-Yet-Signed-off-by while looking
	into the possibility of a more efficient implementation.)

							Thanx, Paul
