[PATCH] Avoid excessive sorting of early_node_map[]
find_min_pfn_for_node() and find_min_pfn_with_active_regions() sort early_node_map[] on every call. This is an excessive amount of sorting and that can be avoided. This patch always searches the whole early_node_map[] in find_min_pfn_for_node() instead of returning the first value found. The map is then only sorted once when required. Successfully boot tested on a number of machines.
