Re: [PATCH V9 1/4] dma-mapping: Rework dma_get_cache_alignment()

I can queue 1 up in the dma-mapping tree, and if I get reviews for
the mips and scsi bits I'd be happy to queue those up as well.

But I think you'd be better off moving patches 3 and 4 to the front
without the dma_get_cache_alignment prototype change so that they can be
merged to stable.
