Linus Torvalds 671df18953 dma-mapping updates for 5.4: 
- add dma-mapping and block layer helpers to take care of IOMMU
    merging for mmc plus subsequent fixups (Yoshihiro Shimoda)
  - rework handling of the pgprot bits for remapping (me)
  - take care of the dma direct infrastructure for swiotlb-xen (me)
  - improve the dma noncoherent remapping infrastructure (me)
  - better defaults for ->mmap, ->get_sgtable and ->get_required_mask (me)
  - cleanup mmaping of coherent DMA allocations (me)
  - various misc cleanups (Andy Shevchenko, me)
