Hey Guilherme,
Thanks for the pointers and confirming these are not regressions, but
known issues. :)

Also, ppc64/s390 are being tracked here:
https://bugs.launchpad.net/ubuntu/+source/makedumpfile/+bug/1851663
It's a common issue, and difficult to debug (if we run tests locally, we can't
reproduce and they succeeed).
Regarding i386, we should remove tests for i386 in Eoan and Focal.
Cheers,
The autopkgtests regressions are unrelated to this SRU.
Sure enough: the patch is for arm64 only, but the archs failing are
i386, ppc64el, and s390x.
The "regressions" also happen with the version in -updates, in the same
way as in -proposed.

Disregard my last comment (#15) ...
I was confused for a second between :
#define PHYS_MASK ((1UL << PHYS_MASK_SHIFT) - 1)
#define PMD_SECTION_MASK((1UL << 40) - 1)
so PMD_SECTION_MASK fix is not found in debian yet.
I'll sponsor the debdiff over the weekend.

At first glance, It seems to be a good candidate for a 'sync' from
debian here.
https://wiki.ubuntu.com/UbuntuDevelopment/Merging#Check_if_its_a_merge_or_a_sync
https://wiki.ubuntu.com/SyncRequestProcess
The fix seems to be found in makedumpfile 'unstable'

Hi Jo,
Thanks for the debdiffs!
The contents look good to me (versioning, dep3 headers)
except that the patch sequence number is missing, and
the changelog lacks a brief description of it.
I just fixed those minor things up, and verified all
debdiffs apply cleanly, quilt push -a applies
