Hi Eric,

The challenging ones are /proc/pid/syscall and seccomp which want to see
all of the system call arguments. I think every architecture always
saves the system call arguments unconditionally, so those cases are
probably not as interesting. But they certain look like they could be
trouble.
Seccomp hasn't yet been implemented on m68k, though I'm working on that
with Adrian. The sole secure_computing() call will happen in
syscall_trace_enter(), so all system call arguments have been saved on
the stack.
Haven't looked at /proc/pid/syscall yet ...
Not supported at present (no HAVE_ARCH_TRACEHOOK for m68k). And the
syscall_get_arguments I wrote for seccomp support only copies the first
five data registers, which are always saved.
Cheers,
Michael
