Subject: lockdep: don't print lockdep taint message for !LOCKDEP
From: Andi Kleen <andi@xxxxxxxxxxxxxx>
I was surprised to see a
Disabling lockdep due to kernel taint
message in my lockdep disabled kernel. This patch ifdefs this message
to not be printed when lockdep is not enabled.
BTW in my case it was due to a thermal event. I'm not sure it's really
needed to disable lockdep on thermal events, but I left this alone for
now.
