Ok, That patch from Chris looks fine to me too.

dma_addr_t and resource_size_t aren't the same, but at least
dma_addr_t should always be the bigger one.

And it does look like nothing else ever takes the address of this
field, so the ones that might want just the resource_size_t part will
at least have enough bits.

So I think Chris' patch is the way to go. I'm assuming I'll get it
through the normal drm tree channels, this doesn't sound _so_ urgent
that I'd need to expedite that patch into my tree and apply it
directly.

Thanks,
