Subject: [PATCH] [PATCH] mm: unbloat get_futex_key

The follow_page changes in get_futex_key have left it with two almost
identical blocks, when handling the rare case of a futex in a nonlinear vma.
get_user_pages will itself do that follow_page, and its additional
find_extend_vma is hardly any overhead since the vma is already cached.  Let's
just delete the follow_page block and let get_user_pages do it.
