Ok, the whole series looks pretty clean, modulo a few mostly 
cosmetic details in the driver itself.

Andrew, you are typically merging dma-mapping.h patches, would 
you like to do these, or can we do it in tip:x86/platform?

It would also be nice if the gents on Cc: would voice objections 
or approval, if any.

Thanks,

	Ingo
