The patch titled
Subject: mem-hotplug: use GFP_HIGHUSER_MOVABLE in, alloc_migrate_target()
has been removed from the -mm tree. Its filename was
mem-hotplug-use-gfp_highuser_movable-in-alloc_migrate_target.patch
This patch was dropped because it was withdrawn
------------------------------------------------------
From: Xishi Qiu <qiuxishi@xxxxxxxxxx>
Subject: mem-hotplug: use GFP_HIGHUSER_MOVABLE in, alloc_migrate_target()
alloc_migrate_target() is called from migrate_pages(), and the page is
always from user space, so we can add __GFP_HIGHMEM directly.
