clear_page_range() walks the page tables across the entire
address space and thus across VMA's.
That's why the macro overrides were necessary, to cope with that.
With Hugh Dickin's stuff, we will be doing clear_page_range() via
VMAs and thus eliminate this ugly stuff.
This has all been spelled out pretty explicitly in the various
threads.
