Merge tag 'dma-mapping-4.13' of git://git.infradead.org/users/hch/dma-mapping
Pull dma-mapping infrastructure from Christoph Hellwig:
"This is the first pull request for the new dma-mapping subsystem
In this new subsystem we'll try to properly maintain all the generic
code related to dma-mapping, and will further consolidate arch code
into common helpers.
This pull request contains:
- removal of the DMA_ERROR_CODE macro, replacing it with calls to
->mapping_error so that the dma_map_ops instances are more self
contained and can be shared across architectures (me)
- removal of the ->set_dma_mask method, which duplicates the
->dma_capable one in terms of functionality, but requires more
duplicate code.
- various updates for the coherent dma pool and related arm code
(Vladimir)
- various smaller cleanups (me)"
