m68k (other than Coldfire) uses syscall_trace for both trace entry
and trace exit. Seccomp support requires separate entry points for
trace entry and exit which are already provided for Coldfire.

Replace syscall_trace by syscall_trace_enter and syscall_trace_leave
in preparation for seccomp support. Check return code of
syscall_trace_enter(), and skip syscall if -1. Return code will be
left at what had been set by ptrace or seccomp (in regs->d0).

No regression seen in testing with strace on ARAnyM.

Thanks for your patch!

  arch/m68k/kernel/entry.S  |  8 +++++---
We need similar changes to arch/m68k/68000/entry.S and
arch/m68k/coldfire/entry.S

Do you have a current defconfig for 68000? I've test compiled my patch with two coldfire defconfigs, but could not find one for m68kclassic ...

Cheers,
