[Andrew Morton]

The quilt patch titled
     Subject: mm/demotion: make toptier_distance inclusive upper bound of toptiers
has been removed from the -mm tree.  Its filename was
     mm-demotion-update-node_is_toptier-to-work-with-memory-tiers-fix-3.patch

This patch was dropped because it was folded into mm-demotion-update-node_is_toptier-to-work-with-memory-tiers.patch

Based on suggestion from Wei Xu, having an inclusive upper bound is
simpler.
