3.11.10.3 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Vladimir Davydov <vdavydov@parallels.com>

commit 695c60830764945cf61a2cc623eb1392d137223e upstream.

The mem_cgroup structure contains nr_node_ids pointers to
mem_cgroup_per_node objects, not the objects themselves.
