The patch titled
Subject: mm: replace CONFIG_FLAT_NODE_MEM_MAP with CONFIG_FLATMEM
has been removed from the -mm tree. Its filename was
mm-replace-config_flat_node_mem_map-with-config_flatmem.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Mike Rapoport <rppt@linux.ibm.com>
Subject: mm: replace CONFIG_FLAT_NODE_MEM_MAP with CONFIG_FLATMEM
After removal of the DISCONTIGMEM memory model the FLAT_NODE_MEM_MAP
configuration option is equivalent to FLATMEM.
Drop CONFIG_FLAT_NODE_MEM_MAP and use CONFIG_FLATMEM instead.
