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?
