    this might work for x64, but even there, are you sure it works even with
    CONFIG_PREEMPT enabled (there the spinlocks are more complex)? It sure
    wont work on x86 so i think we need a generic 'soft PC' solution.

    the alternative would be to unwind the stack - quite some task on some
    platforms ...
