[PATCH] voyager: fix the cpu_possible_map to make voyager boot again 



Right at the moment (thanks to a patch from Andrew), cpu_possible_map on
voyager is CPU_MASK_NONE, which means the machine always thinks it has no
CPUs.  Fix that by doing an early initialisation of the cpu_possible_map
from the cpu_phys_present_map.

(akpm: we aim to please)
