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
