I'd rather see a wmb() instead of eieio() to keep this code non-ppc  specific.  (also, we implement wmb as eieio, so I don't keep the  comment about it being too heavy, unless you mean generically).

wmb() is a sync, smp_wmb() is an eieio.  Andy told me he would not accept a sync in those spots.

And the driver is already ppc-specific; it uses in/out_be32.
