#     Merge tag 'dma-mapping-5.6' of git://git.infradead.org/users/hch/dma-mapping
#     
#     Pull dma-mapping fixes from Christoph Hellwig:
#     
#      - give command line cma= precedence over the CONFIG_ option (Nicolas
#        Saenz Julienne)
#     
#      - always allow 32-bit DMA, even for weirdly placed ZONE_DMA
#     
#      - improve the debug printks when memory is not addressable, to help
#        find problems with swiotlb initialization
#     
#     * tag 'dma-mapping-5.6' of git://git.infradead.org/users/hch/dma-mapping:
#       dma-direct: improve DMA mask overflow reporting
#       dma-direct: improve swiotlb error reporting
#       dma-direct: relax addressability checks in dma_direct_supported
#       dma-contiguous: CMA: give precedence to cmdline
