Ah, of course! That would shorten things up too.
Now that I look closely, I notice that function disclaims being
suitable as a general purpose pte lookup utility. If it works for you,
great, but if not I think it's past time to create such a helper. I
know Ira is looking for one, and I contributed to the proliferation
when I added dev_pagemap_mapping_shift().
