I agree.  Lots of history in this file.  It uses #define because well,
i386 was using #define back in the 90's when Elvis was still alive.
Much of the page table code has been rewritten for simplicity, performance
and ease of maintenance but somehow this has escaped so far.

And I'm wondering if eventually the rewrite should be taken even further
making things fully dynamic.
