[PATCH] powerpc numa: Minor debugging code changes
Add debug statement for map_cpu_to_node; it's useful for cpu hotplug. Clarify debug statement about not finding the numa reference points property. Don't print a meaningless associativity depth (-1) on non-numa systems. Signed-off-by: Nathan Lynch <nathanl@austin.ibm.com> Signed-off-by: Paul Mackerras <paulus@samba.org>
