lockdep: output lock_class key instead of address for forward dependency output
Huang, Ying [Fri, 13 Jun 2008 06:40:17 +0000 (14:40 +0800)]
The key instead of address of lock_class should be output in
/proc/lockdep when forward dependency is output, because key is
output for lock_class itself as identifier too.

This patch is based on x86/auto-latest branch of git-x86 tree, and has
been tested on x86_64 platform.
