  dma-mapping: fix page attributes for dma_mmap_* (2019-08-10 19:52:45 +0200)

----------------------------------------------------------------
dma-mapping fixes for 5.3-rc

 - fix the handling of the bus_dma_mask in dma_get_required_mask, which
   caused a regression in this merge window (Lucas Stach)
 - fix a regression in the handling of DMA_ATTR_NO_KERNEL_MAPPING (me)
 - fix dma_mmap_coherent to not cause page attribute mismatches on
   coherent architectures like x86 (me)

----------------------------------------------------------------
Christoph Hellwig (2):
      dma-direct: fix DMA_ATTR_NO_KERNEL_MAPPING
      dma-mapping: fix page attributes for dma_mmap_*

Lucas Stach (1):
      dma-direct: don't truncate dma_required_mask to bus addressing capabilities
