[PATCH] ppc64: Add NUMA cpu summary at boot

Browse Source 
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
