[PATCH] powerpc/pseries: Fix build error when NUMA=n
As reported by lkp, if NUMA=n we see a build error: arch/powerpc/platforms/pseries/hotplug-cpu.c: In function 'pseries_cpu_hotplug_init': arch/powerpc/platforms/pseries/hotplug-cpu.c:1022:8: error: 'node_to_cpumask_map' undeclared 1022 |node_to_cpumask_map[node]); Use cpumask_of_node() which has an empty stub for NUMA=n, and when NUMA=y does a lookup from node_to_cpumask_map[].
