    Merge tag 'dma-mapping-5.1' of git://git.infradead.org/users/hch/dma-mapping · b7a7d1c1
    Linus Torvalds authored
    Pull DMA mapping updates from Christoph Hellwig:
    
     - add debugfs support for dumping dma-debug information (Corentin
       Labbe)
    
     - Kconfig cleanups (Andy Shevchenko and me)
    
     - debugfs cleanups (Greg Kroah-Hartman)
    
     - improve dma_map_resource and use it in the media code
    
     - arch_setup_dma_ops / arch_teardown_dma_ops cleanups
    
     - various small cleanups and improvements for the per-device coherent
       allocator
    
     - make the DMA mask an upper bound and don't fail "too large" dma mask
       in the remaning two architectures - this will allow big driver
       cleanups in the following merge windows
