Merge git://git.infradead.org/intel-iommu

Pull intel IOMMU updates from David Woodhouse:
 "This patchset improves the scalability of the Intel IOMMU code by
  resolving two spinlock bottlenecks and eliminating the linearity of
  the IOVA allocator, yielding up to ~5x performance improvement and
  approaching 'iommu=off' performance"

* git://git.infradead.org/intel-iommu:
  iommu/vt-d: Use per-cpu IOVA caching
  iommu/iova: introduce per-cpu caching to iova allocation
  iommu/vt-d: change intel-iommu to use IOVA frame numbers
  iommu/vt-d: avoid dev iotlb logic for domains with no dev iotlbs
  iommu/vt-d: only unmap mapped entries
  iommu/vt-d: correct flush_unmaps pfn usage
  iommu/vt-d: per-cpu deferred invalidation queues
  iommu/vt-d: refactoring of deferred flush entries
