Merge tag 'dma-mapping-4.19' of git://git.infradead.org/users/hch/dma-mapping

Pull dma-mapping updates from Christoph Hellwig:

 - 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.
