So far CPU hotplug was ignored for mptable implementations which support it by
having the hotpluggable CPUs marked as disabled during boot.
The current kernel code detects that behaviour and actually deals with it
properly:
[0.00] Intel MultiProcessor Specification v1.4

So far CPU hotplug was ignored for mptable implementations which support it by
having the hotpluggable CPUs marked as disabled during boot.
