Could we have this for stable too please, along with the trivial
subsequent fixup. They are:
c40aaaac1018 ("iommu/vt-d: Gracefully handle DMAR units with no supported address widths")
9def3b1a07c4 ("iommu/vt-d: Don't dereference iommu_device if IOMMU_API is not built")
They apply fairly straightforwardly when backported; let me know if you
want us to send patches.
