From: Mike Rapoport <rppt@xxxxxxxxxxxxx> Subject: mm: rename free_area_init_node() to free_area_init_memoryless_node() free_area_init_node() is only used by x86 to initialize a memory-less nodes. Make its name reflect this and drop all the function parameters except node ID as they are anyway zero.
