The mm-of-the-moment snapshot 2020-04-26-00-15 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 (5.x
or 5.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 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.
https://github.com/hnaz/linux-mm
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 also available at
https://github.com/hnaz/linux-mm
This mmotm tree contains the following patches against 5.7-rc2:

Hi,
I'm seeing lots of build failures in mm/madvise.c.
Is Minchin's patch only partially applied or is it just missing some pieces?
a. mm/madvise.c needs to #include <linux/uio.h>
b. looks like the sys_process_madvise() prototype in <linux/syscalls.h>
has not been updated:
In file included from ../mm/madvise.c:11:0:
../include/linux/syscalls.h:239:18: error: conflicting types for ‘sys_process_madvise’

hm, not sure why these weren't noticed sooner, thanks.
This patchset is looking a bit tired now.
Things to be addressed (might be out of date):

Oleksandr, What's the outcome of this issue?
Do we still need to change based on the comment?
