[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.
