The patch titled
bootmem: revisit bootmem descriptor list handling
has been removed from the -mm tree. Its filename was

------------------------------------------------------
Subject: bootmem: revisit bootmem descriptor list handling
From: Johannes Weiner <hannes@xxxxxxxxxxxx>
link_bootmem handles an insertion of a new descriptor into the sorted list
in more or less three explicit branches; empty list, insert in between and
append. These cases can be expressed implicite.
Also mark the sorted list as initdata as it can be thrown away after boot
as well.
