The patchset adds 55 kbytes to x86_64's mm/*.o and there doesn't appear
to be any way of avoiding this overhead, or of avoiding whatever
runtime overheads are added.

It also adds 18k to arm's mm/*.o and arm doesn't support HMM at all.

So that's all quite a lot of bloat for systems which get no benefit from
the patchset. What can we do to improve this situation (a lot)?
