#     powerpc/pseries: Fix CONFIG_NUMA=n build
#     
#     The build is failing with CONFIG_NUMA=n and some compiler versions:
#     
#       arch/powerpc/platforms/pseries/hotplug-cpu.o: In function `dlpar_online_cpu':
#       hotplug-cpu.c:(.text+0x12c): undefined reference to `timed_topology_update'
#       arch/powerpc/platforms/pseries/hotplug-cpu.o: In function `dlpar_cpu_remove':
#       hotplug-cpu.c:(.text+0x400): undefined reference to `timed_topology_update'
#     
#     Fix it by moving the empty version of timed_topology_update() into the
#     existing #ifdef block, which has the right guard of SPLPAR && NUMA.
#     
#     Fixes: cee5405da402 ("powerpc/hotplug: Improve responsiveness of hotplug change")
