The mm-of-the-moment snapshot 2015-07-06-16-25 has been uploaded to
http://www.ozlabs.org/~akpm/mmotm/
mmotm-readme.txt says
README for mm-of-the-moment:
http://www.ozlabs.org/~akpm/mmotm/
This is a snapshot of my -mm patch queue. Uploaded at random hopefully
more than once a week.
You will need quilt to apply these patches to the latest Linus release (4.x
or 4.x-rcY). The series file is in broken-out.tar.gz and is duplicated in
http://ozlabs.org/~akpm/mmotm/series
The file broken-out.tar.gz contains two datestamp files: .DATE and
.DATE-yyyy-mm-dd-hh-mm-ss. Both contain the string yyyy-mm-dd-hh-mm-ss,
followed by the base kernel version against which this patch series is to
be applied.
This tree is partially included in linux-next. To see which patches are
included in linux-next, consult the `series' file. Only the patches
within the #NEXT_PATCHES_START/#NEXT_PATCHES_END markers are included in
linux-next.
A git tree which contains the memory management portion of this tree is
maintained at git://git.kernel.org/pub/scm/linux/kernel/git/mhocko/mm.git
by Michal Hocko. It contains the patches which are between the
"#NEXT_PATCHES_START mm" and "#NEXT_PATCHES_END" markers, from the series
file, http://www.ozlabs.org/~akpm/mmotm/series.
A full copy of the full kernel tree with the linux-next and mmotm patches
already applied is available through git within an hour of the mmotm
release. Individual mmotm releases are tagged. The master branch always
points to the latest release, so it's constantly rebasing.
http://git.cmpxchg.org/cgit.cgi/linux-mmotm.git/
To develop on top of mmotm git:
$ git remote add mmotm git://git.kernel.org/pub/scm/linux/kernel/git/mhocko/mm.git
$ git remote update mmotm
$ git checkout -b topic mmotm/master
<make changes, commit>
$ git send-email mmotm/master.. [...]
To rebase a branch with older patches to a new mmotm release:
$ git remote update mmotm
$ git rebase --onto mmotm/master <topic base> topic
The directory http://www.ozlabs.org/~akpm/mmots/ (mm-of-the-second)
contains daily snapshots of the -mm tree. It is updated more frequently
than mmotm, and is untested.
A git copy of this tree is available at
http://git.cmpxchg.org/cgit.cgi/linux-mmots.git/
and use of this tree is similar to
http://git.cmpxchg.org/cgit.cgi/linux-mmotm.git/, described above.
This mmotm tree contains the following patches against 4.2-rc1:

I have just created since-4.1 branch in mm git tree
(http://git.kernel.org/?p=linux/kernel/git/mhocko/mm.git;a=summary). It
is based on v4.1 tag in Linus tree and mmotm-2015-07-06-16-25.
I have pulled block/core changes as a pre-requisite for Tejun's cgroup
writeback series which is applied on top (I have cherry picked those
because merging it would pull in way too many changes). I have also
pulled cgroup core changes. I hope I haven't forgotten anything.
As usual mmotm trees are tagged with signed tag
(finger print BB43 1E25 7FB8 660F F2F1 D22D 48E2 09A2 B310 E347)
