From 7e92e6ac7978311bf36b144473d3f09cfd5a9a62 Mon Sep 17 00:00:00 2001

Subject: [PATCH] Add option of 13 for FORCE_MAX_ZONEORDER
This is a hack, but it's what the other distros currently use
for aarch64 with 4K pages so we'll do the same while upstream
decides what the best outcome is (which isn't this).
Upstream Status: RHEL only
