Could you please rebase on the latest commit of the main branch? This will resolve some unrelated FreeBSD CI failures and thus make the CI results clearer.

adding missing PROC_SPROTECT helpers while at it.

c992ac6213276f54d868f317cc5092f8aed4ff54 seems to be a rather arbitrary recent commit. I'd suggest linking dabf006a638fdc44cdcf69731de8ac83959db731 instead, which is the commit that introduced the new constants.
Perhaps with this link: freebsd/freebsd-src@dabf006#diff-769c07b1f90eef1351a20f40593b254f85925859273219036320baa1d086774cR68

Hi, thanks for your contribution! It looks good (to my eyes at least) for the most part

I think it's best to keep PROC_PROCCTL_MD_MIN at the end, it doesn't really have a place between PROC_WXMAP_STATUS and PROC_LOGSIGEXIT_CTL in the original headers

I personally would prefer the PPROT changes in a separate commit (same PR is ok), so they can get a more focused commit message (perhaps with a reference link as well)
