Linux regressions report for mainline [2022-11-06]

["Regzbot (on behalf of Thorsten Leemhuis)" <regressions@leemhuis.info>]

Hi Linus! Below is a slightly edited report from regzbot listing all
regression from this cycle that the bot and I are currently aware of.

Patches for two mm issues are available. I guess Andrew will send
them your way in the next few days (one of them hasn't even hit -next yet).

The amdgpu issue is progressing slowly. The efi issue looks stalled,
will poke the thread tomorrow; maybe there was some progress and I just
missed it.

HTH, Ciao, Thorsten

Hi, this is regzbot, the Linux kernel regression tracking bot.

Currently I'm aware of 4 regressions in linux-mainline. Find the
current status below and the latest on the web:

Bye bye, hope to see you soon for the next report.

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@lists.linux.dev 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.:
