[PATCH] Replace highest_possible_node_id() with nr_node_ids
highest_possible_node_id() is currently used to calculate the last possible node idso that the network subsystem can figure out how to size per node arrays. I think having the ability to determine the maximum amount of nodes in a system at runtime is useful but then we should name this entry correspondingly, it should return the number of node_ids, and the the value needs to be setup only once on bootup. The node_possible_map does not change after bootup. This patch introduces nr_node_ids and replaces the use of highest_possible_node_id(). nr_node_ids is calculated on bootup when the page allocators pagesets are initialized.
