  sh: use generic dma_noncoherent_ops (2018-08-02 13:54:20 +0200)

----------------------------------------------------------------
dma-mapping updates for 4.19

 - a series from Robin to fix bus imposed dma limits by adding a separate
   mask for them to struct device instead of trying to squeeze a second
   meaning out of the existing dma mask as we did before.  This has ACKs
   from the various other subsystems touched
 - a small swiotlb cleanup from Kees (acked by Konrad)
 - conversion of nios2 and sh to the new generic dma-noncoherent code.
   Various other architecture conversions will come through the
   architectures maintainers trees.

----------------------------------------------------------------
Christoph Hellwig (6):
      nios2: use generic dma_noncoherent_ops
      sh: simplify get_arch_dma_ops
      sh: introduce a sh_cacheop_vaddr helper
      sh: use dma_direct_ops for the CONFIG_DMA_COHERENT case
      sh: split arch/sh/mm/consistent.c
      sh: use generic dma_noncoherent_ops

Kees Cook (1):
      swiotlb: clean up reporting

Robin Murphy (9):
      dma-mapping: relax warning for per-device areas
      of/platform: Initialise default DMA masks
      ACPI/IORT: Support address size limit for root complexes
      dma-mapping: Generalise dma_32bit_limit flag
      ACPI/IORT: Set bus DMA mask as appropriate
      of/device: Set bus DMA mask as appropriate
      iommu/dma: Respect bus DMA limit for IOVAs
      ACPI/IORT: Don't set default coherent DMA mask
      OF: Don't set default coherent DMA mask
