From: Guenter Roeck linux@roeck-us.net
commit 9c548bb5823dfcf7a16c6e65976d84d9581208c9 upstream.
sparc:allmodconfig fails to build as follows.
ERROR: "mdesc_release" [drivers/sbus/char/oradax.ko] undefined! ERROR: "sun4v_hvapi_register" [drivers/sbus/char/oradax.ko] undefined! ERROR: "mdesc_get_property" [drivers/sbus/char/oradax.ko] undefined! ERROR: "mdesc_node_by_name" [drivers/sbus/char/oradax.ko] undefined! ERROR: "mdesc_grab" [drivers/sbus/char/oradax.ko] undefined!

The symbols are only available with SPARC64 builds, thus the driver depends on it.
