Russell, aren't you a kernel maintainer, because for fuck sake get real.

I'm not merging bullshit into my tree that has a completely broken API that
has to be maintained for ever. You of all people should understand we
don't break Linux
userspace APIs, and adding a phys addr one is wrong, wrong, wrong, its not
cleanups, its just broken, and I'll never merge it.
