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

[Add a dependency on RHEL_DIFFERENCES]
