kernel/watchdog.c:40:19: warning: symbol
  'watchdog_hardlockup_user_enabled' was not declared. Should it be static?
kernel/watchdog.c:41:19: warning: symbol
  'watchdog_softlockup_user_enabled' was not declared. Should it be static?

These variabled are only used in their defining file, so it should be static.
