I'd love to have some feedback specifically about the API.

I have also some idea about userspace and how to extend the pmalloc
concept to it:

I'll be AFK intermittently for about 2 weeks, so i might not be able to
reply immediately, but from my perspective this would be just the
beginning of a broader hardening of both kernel and userspace that I'd
like to pursue.
