We need to disable all CPUs other than the boot CPU (usually 0) before
attempting to power-off modern SMP machines. This fixes the
hang-on-poweroff issue on my MythTV SMP box, and also on Thomas Gleixner's
new toybox.

There still is a remaining shutdown problem in 2.6.22 with old APM based
systems, but this fix is not the correct one
