I was screwing around with changing some macros in pgtable-3level.h into
static inlines and I quickly ran into some dependency problems.  Mainly,
pgtable-3level.h was included from pgtable.h before __pmd_offset() was
defined, and I wanted to use __pmd_offset() in a function instead of a
macro.

Anyway I have some _really_ rough demonstration of what I would like to
do in the attached patch.  What I want to see is some more explicit
definitions of what the dependencies are in the various header files.
Is this anything that people would like to see expanded?

I haven't even gotten close to moving all of the macros into the ops.h
file, but you can probably get the idea.
