Ingo Molnar [Thu, 23 Apr 2009 07:36:52 +0000 (09:36 +0200)]
Andi Kleen reported this message triggering on non-lockdep kernels:

   Disabling lockdep due to kernel taint

Clarify the message to say 'lock debugging' - debug_locks_off()
turns off all things lock debugging, not just lockdep.

[ Impact: change kernel warning message text ]
