Revision 4399c8bf2b9093696fa8160d79712e7346989c46 authored by Allen Kay on 14 October 2011, 19:32:46 UTC, committed by David Woodhouse on 19 October 2011, 11:06:22 UTC
If target_level == 0, current code breaks out of the while-loop if
SUPERPAGE bit is set. We should also break out if PTE is not present.
If we don't do this, KVM calls to iommu_iova_to_phys() will cause
pfn_to_dma_pte() to create mapping for 4KiB pages.
