The patch titled
Subject: mm: memcontrol: consolidate memory controller initialization
has been removed from the -mm tree. Its filename was
mm-memcontrol-consolidate-memory-controller-initialization.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
From: Johannes Weiner <hannes@xxxxxxxxxxx>
Subject: mm: memcontrol: consolidate memory controller initialization
The initialization code for the per-cpu charge stock and the soft
limit tree is compact enough to inline it into mem_cgroup_init().
