[ Upstream commit c1e150ceb61e4a585bad156da15c33bfe89f5858 ]
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.
