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.
