The patch titled
Subject: mm: kill is_dev_zone() helper
has been removed from the -mm tree. Its filename was
mm-kill-is_dev_zone-helper.patch
This patch was dropped because other changes were merged, which wrecked this patch
------------------------------------------------------
From: Dan Williams <dan.j.williams@xxxxxxxxx>
Subject: mm: kill is_dev_zone() helper
Given there are no more usages of is_dev_zone() outside of 'ifdef
CONFIG_ZONE_DEVICE' protection, kill off the compilation helper.
