Hi Geert,
Thanks for that info, I didn't know about that Amiga port.
I've looked into that implementation and it's similar to what I've done.
But as far as I can tell the code is also incomplete (the trap_c
function doesn't distinguish who caused the trap because
pt_regs->format and pt_regs->vector are pointing to some random
values).
Is the Amiga development active? I can see that the last commit was
about 1 year ago.
Thanks and regards,
Luis Alves

Also, the existing trap exception code doesn't work with 68000 cpu's
since they don't provide the vector in the stack.
arch/m68k/kernel/entry_mm.S (yes, _mm, as Amiga platform code is based
on the m68k "mm" framework) from
http://git.kernel.org/?p=linux/kernel/git/geert/linux-m68k.git;a=shortlog;h=refs/heads/uamiga-untested
should have trap support for 68000.
Never tested on real hardware, though.
Gr{oetje,eeting}s,
