Ulf,

your patch for scall_o32 reminded me of another bug that we still have
in that file.  The SAVE_SOME macro saves only a0-a3 but not a4-a7.  These
however should also be accessible via ptrace(2), so you'll also have to
save a6 / a7 at scall_o32.S:trace_a_syscall.

I'll commit a fix for this into CVS.

  Ralf
