[PATCH] powerpc numa: Support sparse online node map
The powerpc numa code unconditionally onlines all nodes from 0 to the highest node id found, regardless of whether cpus or memory are present in the nodes. This wastes 8K per node and complicates some cpu and memory hotplug situations, such as adding a resource that doesn't map to one of the nodes discovered at boot. Set nodes online as resources are scanned. Fall back to node 0 only when we're sure this isn't a NUMA machine. Instead of defaulting to node 0 for cases of hot-adding a resource which doesn't belong to any initialized node, assign it to the first online node.
