NAK. I don't want to do this, because pmd_is_leaf() is purely about
the guest page tables (the "partition-scoped" radix tree which
specifies the guest physical to host physical translation), not about
anything to do with the Linux process page tables. The guest page
tables have the same format as the Linux process page tables, but they
are managed separately.

If it makes things clearer, I could rename it to "guest_pmd_is_leaf()"
or something similar.
