Subject: [PATCH tip/core/rcu 0/3] CPU hotplug changes for 4.9

Hello!

This series contains a few CPU-hotplug updates:

1.	Provide exact tracking of incoming CPUs, which means that there
	is now a definite point in the CPU-hotplug code at which RCU
	starts paying attention to incoming CPUs.

2.	Get rid of obsolete CPU_STARTING reference, courtesy of Sebastian
	Andrzej Siewior.

3.	Convert rcutorture's CPU-hotplug handling to use the shiny new
	state machine, courtesy of Sebastian Andrzej Siewior.

							Thanx, Paul
