Subject[PATCH] Add note that lockdep is not allowed with non-GPL modules
Hi Ingo,
  can you add this small notice to the lockdep option ?  

Lock dependency infrastructure forces all legacy code which uses lock to now
depend on lockdep_init_map symbol, which is GPL-only.  It means that almost
no modules can work on kernel with CONFIG_LOCKDEP set.  Let's warn user about
that.

vmmon: module license 'unspecified' taints kernel.
vmmon: Unknown symbol lockdep_init_map

				Thanks,
					Petr Vandrovec
