No, but this will.  Tested on a tree which still has MODULE_PARM in it.

Name: Fixe MODULE_PARM warning
Status: Tested on 2.6-bk
Depends: Module/MODULE_PARM-warning.patch.gz
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

There is no __attribute_unused__: use __attribute__((__unused__)).
Also, needs a real MODULE_PARM_ for when gcc doesn't throw it away for us.
