Just re-checked this in order to be sure, and no, the IOMMU faults are
already there prior to XSA-442 for the dom0pvh tests, but they don't
cause issues to osstest, and hence we didn't realize. I just came
across those as I was triaging a different issue and looking at the
serial log.
Hence I won't add any mentions to XSA-442 in the commit message.
Thanks, Roger.
