Do we really need all this? Systems which support physical hotplug
typically have lot's of cpu's (mostly will have atleast > 8). Even if we
really need to identify, then perhaps we can check if ACPI has any hints
regarding the physical hotplug support at boot time (we should check
with Andi Kleen or Len Brown on this).

For now, I think we can keep it simple by using the detected enabled
cpu's.

thanks,
