3   Generic support for BUG()
7   CONFIG_BUG - emit BUG traps.  Nothing happens without this.
10   CONFIG_DEBUG_BUGVERBOSE - emit full file+line information for each BUG
22   2. Implement BUG (and optionally BUG_ON, WARN, WARN_ON)
24      - Implement BUG() to generate a faulting instruction
33        or an actual bug.
