  kdb: Add message about CONFIG_DEBUG_RODATA on failure to install breakpoint (2012-03-22 15:07:16 -0500)

----------------------------------------------------------------
Fixes:
- Fix KDB keyboard repeat scan codes and leaked keyboard events
- Fix kernel crash with kdb_printf() for users who compile new kdb_printf()'s
  in early code
- Return all segment registers to gdb on x86_64
Features:
- KDB/KGDB hook the reboot notifier and end user can control if it stops,
  detaches or does nothing (updated docs as well)
- Notify users who use CONFIG_DEBUG_RODATA to use hw breakpoints
