Short of disabling the printf in sys_ioctl() in sys/kern/sys_generic.c,
the Right Thing To Do™ would be to fix multimedia/motion not to issue
those erroneous ioctls. This was reported (and sometimes fixed) for other
* sysutils/duplicity-devel/ throws ioctl sign-extension ioctl ffffffff80087467
* mt(8): ioctl sign-extension warnings from some mt commands on 64-bit
* Fix fcntl module to accept 'unsigned long' type commands for ioctl(2).
Maybe the respective commits could shed some light on how to do this for
BOFH excuse #417:
Computer room being moved. Our systems are down for the weekend.
