In dom0_construct_pv() and its helpers (covering strict mode) this additionally requires establishing the type of those pages (albeit with zero type references). The earlier establishing of PGT_writable_page | PGT_validated requires the existing places where this gets done (through get_page_and_type()) to be updated: For pages which actually have a mapping, the type refcount needs to be 1. There is actually a related bug that gets fixed here as a side effect: Typically the last L1 table would get marked as such only after get_page_and_type(..., PGT_writable_page). While this is fine as far as refcounting goes, the page did remain mapped in the IOMMU in this case (when "iommu=dom0-strict").

There is actually a related bug that gets fixed here as a side effect: Typically the last L1 table would get marked as such only after get_page_and_type(..., PGT_writable_page). While this is fine as far as refcounting goes, the page did remain mapped in the IOMMU in this case (when "iommu=dom0-strict").
