#     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)"
#
