So, I cleaned that patch and took the chance to simplify things a bit
more and now we give the same guarantees for 32bit and 64bit. We're
still removing a lot more code than we add. I provided a detailed
description and some already existing users.

If you're fine with it I would ask you to please just apply it or if you
prefer I can send a pull request tomorrow. I'm still stuck at the
doctor's office.

I spent most of my day compiling and test i386 kernel and userspace.
Surprisingly, trauma isn't the best teacher because I had completely
forgotten how horrible it all is and I'm glad I'm back in a world where
64bit is a thing.
