The mm-of-the-moment snapshot 2022-03-31-20-37 has been uploaded to

   https://www.ozlabs.org/~akpm/mmotm/

mmotm-readme.txt says

README for mm-of-the-moment:

https://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
https://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 https://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

Doesn't fail here.

Oh... Probably this:

        num_dbs = (pci_resource_len(pdev, 0) - NVME_REG_DBS) /                  
                  (fdev->db_stride * 4);      

The bad config must have 64b resource length. Dimitris, PTAL.

I built last night with the mm tree from github tagged
v5.17-mmotm-2022-03-31-20-37, i386 allmodconfig. It didn't reach the
link stage due to other errors but I looked at fun_dev.o with nm, it
didn't have a reference to __udivdi3. It may need a PAE config, I'll
try that.
