Maybe this series should get a "Cc: stable" tag too?
I don't have a specific commit to provide for Fixes:, but it deals with an issue where sometimes processes return from the machine check handler and hit the same machine check again.
It's hard[1] to hit in v5.8, but somehow gets progressively easier in newer versions.

[1] Initially I thought it didn't happen at all in v5.8. Then wasted a bunch of time trying to bisect. But my "git bisect good" responses turned out to be randomly assigned when I just hadn't tried enough times to make the problem show up.
