So make page_to_mfn and mfn_to_page return mfn_t by default. The __* version are now dropped as this patch will convert all the remaining non-typesafe callers. Only reasonable clean-ups are done in this patch. The rest will use _mfn/mfn_x for the time being. Lastly, domain_page_to_mfn is also converted to use mfn_t given that most of the callers are now switched to _mfn(domain_page_to_mfn(...)). Signed-off-by: Julien Grall Acked-by: Razvan Cojocaru Reviewed-by: Paul Durrant Reviewed-by: Boris Ostrovsky Reviewed-by: Kevin Tian Reviewed-by: Wei Liu Acked-by: Jan Beulich Reviewed-by: George Dunlap Acked-by: Tim Deegan --- Andrew suggested to drop IS_VALID_PAGE in xen/tmem_xen.h. His comment was: "/sigh This is tautological. The definition of a "valid mfn" in this case is one for which we have frametable entry, and by having a struct page_info in our hands, this is by definition true (unless you have a wild pointer, at which point your bug is elsewhere). IS_VALID_PAGE() is only ever used in assertions and never usefully, so instead I would remove it entirely rather than trying to fix it up." I can remove the function in a separate patch at the begining of the series if Konrad (TMEM maintainer) is happy with that.
