This patch add a complete implementation of DMA-mapping API for
devices which have IOMMU support.

Hi Marek,

It looks like this patch breaks no-MMU builds on ARM, at least
according to git bisect.  Here is a link to a linux-next failure:

http://kisskb.ellerman.id.au/kisskb/buildresult/6291233/

arch/arm/mm/dma-mapping.c:726:42: error: 'pgprot_kernel' undeclared
(first use in this function)
make[2]: *** [arch/arm/mm/dma-mapping.o] Error 1

Please have a look, thanks.

Thanks for reporting this issue, I will send a fix in a minute.

Best regards
