Sebastian Andrzej Siewior 5438da977f mm/vmstat: Convert to hotplug state machine ...

Install the callbacks via the state machine, but do not invoke them as we
can initialize the node state without calling the callbacks on all online
CPUs.

start_shepherd_timer() is now called outside the get_online_cpus() block
which is safe as it only operates on cpu possible mask.
