Drop a WARN_ON() if kvm_pfn_to_page() encounters a "reserved" pfn, which in this context means a struct page that has PG_reserved but is not a/the ZERO_PAGE and is not a ZONE_DEVICE page. The usage, via gfn_to_page(), in x86 is safe as gfn_to_page() is used only to retrieve a page from KVM-controlled memslot, but the usage in PPC and s390 operates on arbitrary gfns and thus memslots that can be backed by incompatible memory.
