powerpc/numa: Fix bug in unmap_cpu_from_node
When converting to the new cpumask code I screwed up:
- if (cpu_isset(cpu, numa_cpumask_lookup_table[node])) {
- cpu_clear(cpu, numa_cpumask_lookup_table[node]);
+ if (cpumask_test_cpu(cpu, node_to_cpumask_map[node])) {
+ cpumask_set_cpu(cpu, node_to_cpumask_map[node]);
This was introduced in commit 25863de07af9 (powerpc/cpumask: Convert NUMA code
to new cpumask API)
Fix it.
