FWIW I'm presuming this work will go via a powerpc tree not libata... 
Generally that's not the case, but here it's largely an arch-specific work.

Ok, that works. I was thinking of letting this patch go through libata,
and do the removal through the powerpc merge path. But I can do both
through powerpc.

Are you going to send me a patch to do this addition plus the removal
of the old stuff, or do you want me to merge this patch as is?

Paul.
