When CONFIG_NUMA is not set, build fail with: arch/powerpc/platforms/pseries/hotplug-cpu.c:335:4: error: déclaration implicite de la fonction « update_numa_cpu_lookup_table » [-Werror=implicit-function-declaration]
So we have to add update_numa_cpu_lookup_table as an empty function when CONFIG_NUMA is not set.
