Subject: mmotm git tree since-4.7 branch created (was: mmotm 2016-07-28-16-33
 uploaded)

I have just created since-4.7 branch in mm git tree
(http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It
is based on v4.7 tag in Linus tree and mmotm-2016-07-28-16-33
I have pulled cgroups, libnvdim and tip/mm trees because they seem to
have changes which might be needed. I had to drop the dma update pile
because it was causing just too many conflicts. Let me know if other
changes would be of a benefit.

Also note that based on Fenguang request there has been auto-latest
branch create which always tracks the last since-X.Y. This branch will
get rebased after each since-X.Y+1 is released.

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