That's a good point... I don't think we do. Maybe we should.
Well, basically our approach was that mmiowb() is a pain in the neck,
nobody (ie. driver writers) really understands what it's for, and so
it's either not there or misused. So we didn't want to introduce it for
powerpc, but instead did the trick above in order to -slightly- improve
our writel (ie avoid a sync -after- the write) .
