[Paul Durrant <paul@xxxxxxx>]

From: Paul Durrant <pdurrant@xxxxxxxxxx>

v4:
 - Added three more patches to convert root_entry, context_entry and
   dma_pte to bit fields.

Paul Durrant (14):
  x86/iommu: re-arrange arch_iommu to separate common fields...
  x86/iommu: add common page-table allocator
  x86/iommu: convert VT-d code to use new page table allocator
  x86/iommu: convert AMD IOMMU code to use new page table allocator
  iommu: remove unused iommu_ops method and tasklet
  iommu: flush I/O TLB if iommu_map() or iommu_unmap() fail
  iommu: make map, unmap and flush all take both an order and a count
  remove remaining uses of iommu_legacy_map/unmap
  common/grant_table: batch flush I/O TLB
  iommu: remove the share_p2m operation
  iommu: stop calling IOMMU page tables 'p2m tables'
  vtd: use a bit field for root_entry
  vtd: use a bit field for context_entry
  vtd: use a bit field for dma_pte
