nonboot cpu on SMP suspend

Hi all,

I'm curious why we need to un-plug all the nonboot cpus before suspend
and start them all over again after the suspend(ACPI sleep)? I mean
if we can bring the booting cpu back to the exact state as before
suspend, why can't we just do the same for non-booting cpus? And that
will be much faster. Any thought? Thanks.
