This went in, didn't it?

Some of this went in too, I think?

In v2 the title had changed to "x86: support AVX10", dealing with a first
aspect of AVX10.2 as well. I have long completed AVX10.2 work, yet there
was little reason to re-post without having got any feedback.

I think you want to remove this from the list. While I have completed work
there, I'm not fancying re-basing ahead of the AVX10 work, and hence that
needs to go in first anyway. Which seems unlikely enough at this point, for
4.20.

Isn't this the same as ...

This series was posted only this week, and upon asking it was clarified that
it's indeed not aiming at 4.20.
