Yeah, I'm not a huge fan of doing that, either. But, I'm not sure what
the alternatives are. We could basically copy smaps_pte_entry() to
smaps_pmd_entry(), and then try to make pmd variants of all of the pte
functions and macros we call in there.

I know there's a least a bit of precedent in the hugetlbfs code for
doing things like this, but it's not a _great_ excuse. :)
