mempool are generally used for GFP_NOIO, so this wont benefit all that
much because might_alloc currently only checks GFP_NOFS.  But it does
validate against mmu notifier pte zapping, some might catch some drivers
doing really silly things, plus it's a bit more meaningful in what we're
checking for here.
