3.16.57-rc1 review patch. If anyone has any objections, please let me know. ------------------ From: Corentin Labbe <clabbe@xxxxxxxxxxxx> commit c1e150ceb61e4a585bad156da15c33bfe89f5858 upstream. When CONFIG_NUMA is not set, the build fails with: arch/powerpc/platforms/pseries/hotplug-cpu.c:335:4: error: déclaration implicite de la fonction « update_numa_cpu_lookup_table » So we have to add update_numa_cpu_lookup_table() as an empty function when CONFIG_NUMA is not set.
