This version of the series uses u64 only for guest physical addresses and error return values: * u64 pfn is replaced by struct page * u64 level is replaced by int level * u64 tdr and u64 tdvpr are replaced by structs that contain struct page for them as well as for tdcs and tdcx. A couple functions are also moved over from KVM to tdx.h static inline u64 mk_keyed_paddr(u16 hkid, struct page *page) static inline int pg_level_to_tdx_sept_level(enum pg_level level) The plan is to include these in kvm.git together with their first user.
