The patch titled
Subject: mm/page_alloc.c: skip ZONE_MOVABLE if required_kernelcore is larger than totalpages
has been removed from the -mm tree. Its filename was
mm-skip-if-required_kernelcore-is-larger-than-totalpages.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Xishi Qiu <qiuxishi@xxxxxxxxxx>
Subject: mm/page_alloc.c: skip ZONE_MOVABLE if required_kernelcore is larger than totalpages
If kernelcore was not specified, or the kernelcore size is zero
(required_movablecore >= totalpages), or the kernelcore size is larger
than totalpages, there is no ZONE_MOVABLE. We should fill the zone with
both kernel memory and movable memory.
