Your step 1 is the bit that strikes me as invasive here - that's not
something I'd be touching in a stable release if I didn't have to, it's
visible to half the kernel in an area where we clearly don't have ideal
review of the code (otherwise we'd not have a problem here in the first
place) which seems totally disproportionate to the benefit here. We're
talking about an issue which affects one device which is used only on
Marvell systems here.

I think everyone agrees that this is the best route forward for future
kernels.
