The patch titled
Subject: mm: use numa_mem_id() in alloc_pages_node()
has been removed from the -mm tree. Its filename was
mm-use-numa_mem_id-in-alloc_pages_node.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Vlastimil Babka <vbabka@xxxxxxx>
Subject: mm: use numa_mem_id() in alloc_pages_node()
alloc_pages_node() might fail when called with NUMA_NO_NODE and
__GFP_THISNODE on a CPU belonging to a memoryless node. To make the
local-node fallback more robust and prevent such situations, use
numa_mem_id(), which was introduced for similar scenarios in the slab
context.
