Nathan Lynch 558f86493d powerpc/numa: document topology_updates_enabled, disable by default 
Changing the NUMA associations for CPUs and memory at runtime is
basically unsupported by the core mm, scheduler etc. We see all manner
of crashes, warnings and instability when the pseries code tries to do
this. Disable this behavior by default, and document the switch a bit.
