Nouveau does not currently have logic to implement this as a library function. Even though such a library could be written, there's no big advantage to do it that way for now given that int64 is a very uncommon use-case. Allow a driver to expose INT64 without supporting division and modulo operations. Signed-off-by: Ilia Mirkin <imirkin@alum.mit.edu> Reviewed-by: Nicolai Hähnle <nicolai.haehnle@amd.com>
