The patch titled

This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Joonsoo Kim <iamjoonsoo.kim@xxxxxxx>
Subject: mm/vmstat: make node_page_state() handles all zones by itself
node_page_state() manually adds statistics per each zone and returns total
value for all zones. Whenever we add a new zone, we need to consider this
function and it's really troublesome. Make it handle all zones by itself.
