The mm-of-the-moment snapshot 2020-07-27-18-18 has been uploaded to

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 5.8-rc7:

As is usually the case with your reports, I can't figure out how to
reproduce it. I copy then .config, run `make oldconfig' (need to hit
enter a zillion times because the .config is whacky) then the build
succeeds. What's the secret?
Anyway,
#ifdef CONFIG_CONTIG_ALLOC
...
/* [start, end) must belong to a single zone. */
static int __alloc_contig_migrate_range(struct compact_control *cc,
unsigned long start, unsigned long end)
and
#if defined CONFIG_COMPACTION || defined CONFIG_CMA
...
struct compact_control {
so we presumably have
CONFIG_CONTIG_ALLOC=y
CONFIG_COMPACTION=n
CONFIG_CMA=n
which is indeed what's in your config file.
But
config CONTIG_ALLOC
def_bool (MEMORY_ISOLATION && COMPACTION) || CMA
says this is an improper combination. And `make oldconfig' fixes it up.
What's happening here?

Argh, select strikes again.
So I guess VIRTIO_MEM should also select COMPACTION?

I was not aware that there was a problem. cp .config and make oldconfig
should be sufficient -- and I don't understand why you would need to hit
enter many times.
I repeated this on my system without having to answer any oldconfig prompts
and still got build errors.
There is no secret that I know of, but it would be good to get to the
bottom of this problem.

I usually do 'olddefconfig', which is the same as oldconfig but it
selects the default value of the symbols that are new. This usually
happens for me if I am flipping around in different trees like mainline
and next, where there might be new or different symbols between them.

Well the first thing I hit was
Support for big SMP systems with more than 8 CPUs (X86_BIGSMP) [N/y/?] (NEW)
and your .config doesn't mention that.
make mrproper
cp ~/config-randy .config
make oldconfig

It's an x86_32 symbol and my config was for x86_64.

If it helps with Enter:
yes '' | make oldconfig
Works 99.99% of the time except when there is numeric/string option
without default value.

Okay, I think I am confused. I thought we had that already fixed. @mst
