We have hit a few customer issues with the topology update code (VPHN and PRRN). It would be nice to be able to debug the notifications coming from the hypervisor in both cases to the LPAR, as well as to disable responding to the notifications at boot-time, to narrow down the source of the problems. Add a basic level of such functionality, similar to the numa= command-line parameter. We already have a toggle in /proc/powerpc/topology_updates that allows run-time enabling/disabling, so the updates can be started at run-time if desired. But the bugs we've run into have occured during boot or very shortly after coming to login, and have resulted in a broken NUMA topology.
