This won't work right with the maxcpus commandline option set to
something lower than the number of cpus present on the system. This
option controls how many cpus the system tries to bring up during boot,
while still allowing one to hotplug the rest of them later. If you do
hotplug them later, system_state will no longer be SYSTEM_BOOTING, and
this code won't do what it needs to do.
