[S390] cpu topology: fix cpu_core_map initialization

Browse source

Common code doesn't call arch_update_cpu_topology() anymore on
cpu hotplug. But our architecture backend relied on that in order to
update the cpu_core_map. For machines without cpu topology support
this leads uninitialized cpu_core_maps for later on added cpus.

To solve this just initialize the maps with cpu_possible_map, since
that will be always valid for machines without topology support.
