    At first I thought these would be useless (they're the *user* state
    and aren't directly relevant to the kernel), but then I realized that
    they could be extremely valuable: they contain the syscall args. Do
    they display in OOPS dumps? It might be nice to add orig_ax to the
    regs display too so we get the syscall nr as well.
