You're right, my bad. I looked at setup_smp() and how it walked through
every CPU in the firmware, but it doesn't actually ever set the possible
map, it fills in just hwrpb_cpu_present_mask (which is then then only used
_later_ to set cpu_possible_map for some silly reason).

As far as I can tell, "hwrpb_cpu_present_mask" is just wrong, and the code
_should_ be using cpu_possible_map.

rth? Ivan?
