    kernel - Fix cpu lockup on resume after entering the debugger
    
    * Xcpustop was not testing ipending on resume.  Since Xcpustop STIs
      it is possible for it to receive further interrupts while stopped
      which can cause ipending to be set.
    
    * Use doreti instead of doreti_iret.   doreti will test ipending,
      fpending, the per-cpu flags.
    
    * Change the semantics to work more similarly to normal interrupt vectors.
    
    * Note that dumping is still problematic.
