Subject: [PATCH 0/1] lockdep: fix warning: print_lock_trace defined but not used


I ran across this minor warning while building against today's linux.git.

The proposed trivial fix leaves it a little fragile from a "what if someone
adds a new call to print_lock_trace()" point of view, but I believe that it
makes the current combination of ifdefs accurate, anyway.
