The patch titled
Add __GFP_MOVABLE for callers to flag allocations from low memory that may be migrated
has been removed from the -mm tree. Its filename was
add-__gfp_movable-for-callers-to-flag-allocations-from-low-memory-that-may-be-migrated.patch
This patch was dropped because it was folded into add-__gfp_movable-for-callers-to-flag-allocations-from-high-memory-that-may-be-migrated.patch
------------------------------------------------------
Subject: Add __GFP_MOVABLE for callers to flag allocations from low memory that may be migrated
From: Mel Gorman <mel@xxxxxxxxx>
This patch flags the allocations from low memory that may be migrated.
A GFP_USER_MOVABLE similar to GFP_HIGH_MOVABLE is not provided in this patch
because it would only be used once. This patch uses __GFP_MOVABLE twice for a
GFP_USER and a GFP_NOIO allocation. There is little point defining
GFP_*_MOVABLE for one use unless people feel it would help self-documentation.
