Pull swiotlb update from Konrad Rzeszutek Wilk:
 "Feature:
   - Use dma addresses instead of the virt_to_phys and vice versa
     functions.

  Remove the multitude of phys_to_virt/virt_to_phys calls and instead
  operate on the physical addresses instead of virtual in many of the
  internal functions.  This does provide a speed up in interrupt
  handlers that do DMA operations and use SWIOTLB."

  swiotlb: Do not export swiotlb_bounce since there are no external consumers
  swiotlb: Use physical addresses instead of virtual in swiotlb_tbl_sync_single
  swiotlb: Use physical addresses for swiotlb_tbl_unmap_single
  swiotlb: Return physical addresses when calling swiotlb_tbl_map_single
  swiotlb: Make io_tlb_overflow_buffer a physical address
  swiotlb: Make io_tlb_start a physical address instead of a virtual one
  swiotlb: Make io_tlb_end a physical address instead of a virtual one
