syscall_trace_enter and syscall_trace_leave for m68k w/MMU

Hello!

Michael and I have been working on SECCOMP in SuperH and successfully added
the missing pieces yesterday [1].

We're now looking into what needs to be done for m68k and I have noticed that
syscall_trace_enter and syscall_trace_leave - which needs to be touched for
SECCOMP support - are available on ColdFire and non-MMU targets for m68k.

Is there a particular reason for that? Looking at 68000/entry.S, I can see
that both functions are invoked [2] so I'm not sure why they are built
for CONFIG_COLDFIRE and !CONFIG_MMM only.

Any ideas?

Adrian
