First batch of dma-mapping changes for 4.20:

Browse source 
- 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)

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)"
