Subject: linux-next: manual merge of the akpm tree with the cgroup tree

Hi Andrew,

Today's linux-next merge of the akpm tree got a conflict in
mm/memcontrol.c between commit ab5196c202c6 ("memcg: make
mem_cgroup_reparent_charges non failing") from the cgroup tree and commit
"memcg: destroy memcg caches" from the akpm tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).

Cheers,
