History
Linus Torvalds 2382dc9a3e dma mapping changes for Linux 4.16: 
This pull requests contains a consolidation of the generic no-IOMMU code,
 a well as the glue code for swiotlb.  All the code is based on the x86
 implementation with hooks to allow all architectures that aren't cache
 coherent to use it.  The x86 conversion itself has been deferred because
 the x86 maintainers were a little busy in the last months.

Merge tag 'dma-mapping-4.16' of git://git.infradead.org/users/hch/dma-mapping

Pull dma mapping updates from Christoph Hellwig:
 "Except for a runtime warning fix from Christian this is all about
  consolidation of the generic no-IOMMU code, a well as the glue code
  for swiotlb.

  All the code is based on the x86 implementation with hooks to allow
  all architectures that aren't cache coherent to use it.

  The x86 conversion itself has been deferred because the x86
  maintainers were a little busy in the last months"
