[PATCH] ppc64: Add NUMA cpu summary at boot
We used to print a NUMA cpu summary at boot before the hotplug cpu code was added. This has been useful for catching machine configuration as well as firmware bugs in the past. This patch restores that functionality. An example of the output is: Node 0 CPUs: 0-7 Node 1 CPUs: 8-15 Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
