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

Hi all,

Today's linux-next merge of the akpm-current tree got a conflict in:

  mm/memcontrol.c

between commit:

  0f0cace35fa6 ("mm, memcg: mark cgroup_memory_nosocket, nokmem and noswap as __ro_after_init")

from the percpu tree and commits:

  dfe14954c6e4 ("mm: memcg/slab: don't create kmalloc-cg caches with cgroup.memory=nokmem")
  3fd971b13287 ("mm-memcg-slab-create-a-new-set-of-kmalloc-cg-n-caches-v5")
  53270d6d0c1f ("mm-memcg-slab-create-a-new-set-of-kmalloc-cg-n-caches-v5-fix")

from the akpm-current tree.

I fixed it up (see below) and can carry the fix as necessary. This
is now fixed as far as linux-next is concerned, but any non trivial
conflicts should be mentioned to your upstream maintainer when your tree
is submitted for merging.  You may also want to consider cooperating
with the maintainer of the conflicting tree to minimise any particularly
complex conflicts.

Andrew, you may want to look at commit

  4d5c8aedc8aa ("mm, memcg: introduce mem_cgroup_kmem_disabled()")

from the percpu tree.
