Merge tag 'dma-mapping-4.20' of git://git.infradead.org/users/hch/dma-mapping
Pull dma mapping updates from Christoph Hellwig:
"First batch of dma-mapping changes for 4.20.
There will be a second PR as some big changes were only applied just
before the end of the merge window, and I want to give them a few more
days in linux-next.
Summary:
- mostly more consolidation of the direct mapping code, including
converting over hexagon, and merging the coherent and non-coherent
code into a single dma_map_ops instance (me)
- cleanups for the dma_configure/dma_unconfigure callchains (me)
- better handling of dma_masks in odd setups (me, Alexander Duyck)
- better debugging of passing vmalloc address to the DMA API (Stephen
Boyd)
- CMA command line parsing fix (He Zhe)"
