Subject: clean up the DMA mapping headers
Hi all,
this series cleans up the dma-mapping headers by moving everything not
required by normal drivers out of <linux/dma-mapping.h> into a new
<linux/dma-map-ops.h> and then folding most other DMA mapping related
headers either into the new dma-map-ops.h one, or by moving them to
kernel/dma/ and thus out of the global scope. A bunch of cleanups
for the DMA CMA code are thrown in as well, as they help keeping the
exposed bits in the header small.
