Merge git://git.infradead.org/intel-iommu
Pull IOMMU fixes from David Woodhouse:
"Two minor fixes.
The first fixes the assignment of SR-IOV virtual functions to the
correct IOMMU unit, and the second fixes the excessively large (and
physically contiguous) PASID tables used with SVM"
* git://git.infradead.org/intel-iommu:
iommu/vt-d: Fix PASID table allocation
iommu/vt-d: Fix IOMMU lookup for SR-IOV Virtual Functions
