Subjectmmotm git tree since-4.12 branch created (was: mmotm 2017-07-06-16-18 uploaded)
I have just created since-4.12 branch in mm git tree
(http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It
is based on v4.12 tag in Linus tree and mmotm-2017-07-06-16-18.

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

I have pulled tip/smp/hotplug and tip/x86-mm-for-linus for dependencies.
I had to revert "x86: fix fortified memcpy" because it fails to compile
on x86 32b.

The shortlog says:
