      x86,kgdb: Fix hw breakpoint regression · ba773f7c
      Jason Wessel authored
      HW breakpoints events stopped working correctly with kgdb
      as a result of commit: 018cbffe
      (Merge commit 'v2.6.33' into perf/core).
      
      The regression occurred because the behavior changed for setting
      NOTIFY_STOP as the return value to the die notifier if the breakpoint
      was known to the HW breakpoint API.  Because kgdb is using the HW
      breakpoint API to register HW breakpoints slots, it must also now
      implement the overflow_handler call back else kgdb does not get to see
      the events from the die notifier.
      
      The kgdb_ll_trap function will be changed to be general purpose code
      which can allow an easy way to implement the hw_breakpoint API
      overflow call back.
