The patch titled
Subject: mm: use free_area_init() instead of free_area_init_nodes()
has been removed from the -mm tree. Its filename was
mm-use-free_area_init-instead-of-free_area_init_nodes.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Mike Rapoport <rppt@xxxxxxxxxxxxx>
Subject: mm: use free_area_init() instead of free_area_init_nodes()
free_area_init() has effectively became a wrapper for
free_area_init_nodes() and there is no point of keeping it. Still
free_area_init() name is shorter and more general as it does not imply
necessity to initialize multiple nodes.
Rename free_area_init_nodes() to free_area_init(), update the callers and
drop old version of free_area_init().
