#     Merge tag 'dma-mapping-4.21-1' of git://git.infradead.org/users/hch/dma-mapping
#     
#     Pull dma-mapping fixes from Christoph Hellwig:
#      "Fix various regressions introduced in this cycles:
#     
#        - fix dma-debug tracking for the map_page / map_single
#          consolidatation
#     
#        - properly stub out DMA mapping symbols for !HAS_DMA builds to avoid
#          link failures
#     
#        - fix AMD Gart direct mappings
#     
#        - setup the dma address for no kernel mappings using the remap
#          allocator"
#     
#     * tag 'dma-mapping-4.21-1' of git://git.infradead.org/users/hch/dma-mapping:
#       dma-direct: fix DMA_ATTR_NO_KERNEL_MAPPING for remapped allocations
#       x86/amd_gart: fix unmapping of non-GART mappings
#       dma-mapping: remove a few unused exports
#       dma-mapping: properly stub out the DMA API for !CONFIG_HAS_DMA
#       dma-mapping: remove dmam_{declare,release}_coherent_memory
#       dma-mapping: implement dmam_alloc_coherent using dmam_alloc_attrs
#       dma-mapping: implement dma_map_single_attrs using dma_map_page_attrs
