[GIT PULL] uml-for-7.1-rc1

Hi Linus,

UML doesn't have a lot of content right now. However, I should
note that Michael Bommarito, who shows up here with a build fix,
has been doing a sort of (LLM-assisted) security audit, so we'll
likely be back after -rc1 with fixes.

Please pull and let us know if there's any problem.

Thanks,
johannes
