Formerly, when we received a PRRN rtas event, device tree updating was performed in the kernel and the actual topology updating was performed in userspace. This was necessary as in order to update the topology for memory, we must perform a hot remove and a subsequent hot add and until recently, memory hotplug was not included in the kernel. Since memory hotplug is now available, this patchset moves the PRRN topology updating into the kernel.
