    Fair enough. How about making the layout in that structure identical to
    the 64-bit pt_regs though? I don't know if we need that at any time,
    but my feeling is that it is nicer than a slightly different random
    layout, e.g. if someone wants to extend gdb to look at checkpointed
    process dumps.
