I was actually thinking the same with you, and the good news is, it's
recently moved into tools/ by Dave Young:

commit c6dd897f3bfc54a44942d742d6dfa842e33d88e0
Author: Dave Young <dyoung@...hat.com>
Date:   Wed Mar 28 14:42:55 2012 -0700

    mm: move page-types.c from Documentation to tools/vm

Thanks,
Fengguang
