All use the same set of ioctl() codes that are peculiar to the synclink drivers.
Defining compat_ioctl() seems to be the best way, but that will require modifying the base tty code to allow the individual tty drivers to register compat_ioctl().
Currently the tty file ops do not include that and tty_io.c does not register a compat_ioctl(), instead relying on compat_ioctl.h and compat_ioctl.c
