Subject: [PATCH] voyager: fix cpu bootmaps

commit 98a79d6a50181ca1ecf7400eda01d5dc1bc0dbf0
Author: Rusty Russell <rusty@...tcorp.com.au>

    cpumask: centralize cpu_online_map and cpu_possible_map

Broke voyager largely because it currently initialises the
possible_map by copying, which isn't possible in the new scheme.  Fix
this by using init_cpu_possible() instead and tidy up other of the
cpumask declarations which now have global variables.
