Hi Tim,
the change set comes indeed form the s390x/KVM developers at IBM and is
signed by the upstream maintainer - so it's fully backed by them.

The tests are - like you assumed - not trivial, hence unit tests were
written and run.

It's always a balance on what to incl. in this submission to the kernel
team's mailing-list and what I leave at the Launchpad bug.
The LP bug contains in comment #1 (lower part) some "Notes on
backport<s>",that briefly describe the what and what.
I think that's what you were roughly looking for:
(One may find some more details like stats and a lengthy SRU Justification).

I understand you that you want more details on the backport as part of the
PR submission - will keep that in mind for the next time ...

Thx, for your feedback and ACK,
Bye, Frank
