mm: add new lru for page promotion An active refereced page marked access indicates a hot page. If this page is referenced on a node with a promotion target, move this page from the active lru to a new promotion candidate lru. When this node is scanned later, pages in this lru will attempt to promote to their higher performing target. Signed-off-by: Keith Busch <keith.busch@intel.com>
