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. Signed-off-by: Nathan Lynch <nathanl@linux.ibm.com> Signed-off-by: Michael Ellerman <mpe@ellerman.id.au>
