Pointers should be printed with %p.

mtod() returns a pointer to a data area casted to some type;
in this case you probably want it casted to an "int *" and
extracted, i.e. "on_off = *(mtod(m, int *))".

You don't need to have it physically to at least test compile;
"make universe" is there to test all of them.

This one I've already fixed.

They're not supposed to be redeclared.  I haven't looked if what
you have in compat32/syscalls.master will work, but it's at least
clear now that it hasn't been tested.  To test it, you'd set up
an amd64 box with SCTP and try to run a 32-bit application that
calls these syscalls, and make sure they work.
