Subject: since-3.17 branch opened for mm git tree (was: Re: mmotm
 2014-10-15-16-57 uploaded)

I have just created since-3.17 branch in mm git tree
(http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It
is based on v3.17 tag in Linus tree and mmotm-2014-10-15-16-57.

I have pulled some cgroup wide and percpu changes from Tejun which were
targeted at 3.18 to help memcg dependencies.

As usual mmotm trees are tagged with signed tag
(finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347)
