Pull kgdb update from Daniel Thompson:
 "The entire changeset for kgdb this cycle is a single two-line change
  to remove some deadcode that, had it not been dead, would have called
  strncpy() in an unsafe manner.

  To be fair there were other modest clean ups were discussed this cycle
  but they are not finalized and will have to wait until next time"
