Linux regressions report for mainline [2023-12-10]

[Regzbot (on behalf of Thorsten Leemhuis)]

Hi Linus. Find below the list of regressions by bot currently tracks.
But first let let me mention a few things manually:

* Remember the "Blank screen on boot of Linux 6.5 and later on Lenovo
ThinkPad L570" regression?[1]. Shortly before releasing 6.6 you wrote
"But if this is not fixed by -rc1, we'll just revert it." [2]. I might
have missed something, but it afaics is still not fixed; there was an
attempt to fix this, but maintainers were not happy and then nothing
happened anymore -- at least unless I missed something [3].

[2] https://lore.kernel.org/all/CAHk-=wiX0j=8DB0EbCheAAfcx2z99QUZMTeJUxSBGpb0J5pjVg@xxxxxxxxxxxxxx/
[3] https://lore.kernel.org/all/20231108024613.2898921-1-chenhuacai@xxxxxxxxxxx/

* The Apparmor stuff from Stéphane I CCed you on a few days ago is in
below list of tracked 6.7 regressions; just mentioning this slightly
complicated regression (one we might have to live with due to the
security aspect, but that's your call, I didn't even look closer) in case the CC fall through the crack due to you traveling:
https://lore.kernel.org/regressions/CA%2Benf=u0UmgjKrd98EYkxFu7FYV8dR1SBYJn_1b0Naq=3twbbQ@xxxxxxxxxxxxxx/

* Most of the other 6.7 issues I track are being dealt with afaics,
except for one: it seems a amggpu change broke something for users that
haven't updated their firmware. A amd dev acked the problem mid Nov, but
since then it seems nothing has happened to address this; I'll prod the
devs again tomorrow:

Ciao, Thorsten

Thanks for your attention, have a nice day!

  Regzbot, your hard working Linux kernel regression tracking robot


P.S.: Wanna know more about regzbot or how to use it to track regressions
for your subsystem? Then check out the getting started guide or the
reference documentation:

https://gitlab.com/knurd42/regzbot/-/blob/main/docs/getting_started.md
https://gitlab.com/knurd42/regzbot/-/blob/main/docs/reference.md

The short version: if you see a regression report you want to see
tracked, just send a reply to the report where you Cc
regressions@xxxxxxxxxxxxxxx with a line like this:

#regzbot introduced: v5.13..v5.14-rc1

If you want to fix a tracked regression, just do what is expected
anyway: add a 'Link:' tag with the url to the report, e.g.:
