*	dma/direct: Handle the memory encryption bit in common code	Christoph Hellwig	2018-03-20	1	-23/+2
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	Give the basic phys_to_dma() and dma_to_phys() helpers a __-prefix and add the memory encryption mask to the non-prefixed versions. Use the __-prefixed versions directly instead of clearing the mask again in various places.

*	dma-mapping: move swiotlb arch helpers to a new header	Christoph Hellwig	2018-01-10	1	-0/+30
	phys_to_dma, dma_to_phys and dma_capable are helpers published by architecture code for use of swiotlb and xen-swiotlb only. Drivers are not supposed to use these directly, but use the DMA API instead. Move these to a new asm/dma-direct.h helper, included by a linux/dma-direct.h wrapper that provides the default linear mapping unless the architecture wants to override it. In the MIPS case the existing dma-coherent.h is reused for now as untangling it will take a bit of work. Signed-off-by: Christoph Hellwig <hch@lst.de> Acked-by: Robin Murphy <robin.murphy@arm.com>
