I pushed the recent v9 set where I remove the dep on ARCH_GEMINI
and the autobuilders complain a lot about the use of dma_to_pfn()
which turns out to be a ARM thing from <asm/dma-mapping.h>
included from <linux/dma-mapping.h>.

I will try switching to functions from the generic dma-mapping API
and fix it up and send a v10.
