The patch titled
Subject: mm, memory_hotplug: use node instead of zone in can_online_high_movable
has been removed from the -mm tree. Its filename was
mm-memory_hotplug-use-node-instead-of-zone-in-can_online_high_movable.patch
This patch was dropped because it was merged into mainline or a subsystem tree

From: Michal Hocko <mhocko@xxxxxxxx>
Subject: mm, memory_hotplug: use node instead of zone in can_online_high_movable
The primary purpose of this helper is to query the node state so use the
node id directly. This is a preparatory patch for later changes.
This shouldn't introduce any functional change
