There is a deadlock scenario between lockdep and rcu when rcu nocb feature is enabled, just as following call stack:
I have pulled this into -rcu for further review and testing.
If someone else (for example, the lockdep folks) would like to take this:

FWIW, I add this patch and another one [1] to my tree:
git://git.kernel.org/pub/scm/linux/kernel/git/boqun/linux.git lockdep
(based on today's tip/locking/core)
I figured I have time to handle lockdep-only patches, which shouldn't be a lot. So Ingo & Peter, I'm happy to help. If you need me to pick up lockdep patches and send a PR against tip/master or tip/locking/core, please let me know.
Sorry, I've been hopelessly behind on everything. Yes it would be nice if you could help vacuum up some of the lockdep patches.
Glad I can help! I will send a PR to tip tree between rc2 and rc3.
