Just make mmiowb() strong enough on those platforms. There's really no

It's just horribly slow and an overkill if it's only ordering of
consecutive writes rather than ordering of a read after a write that has
to be guaranteed. But perhaps we could keep abusing wmb() for the
former...
Depends on where it's happening. If it's the CPU doing it before it hits
the bus then wmb() would probably be ok.
