Gah!!! I forgot to label the RCU-lockdep stuff "RFC"!!! Could you please rewind tip/core/rcu back to b6407e8639 ("rcu: Give different levels of the rcu_node hierarchy distinct lockdep names")?
I have fixes for many of the warnings below, both as modifications to uses of RCU and as modifications to the check code itself. But I have been building a new patchsets rather than keeping patches on top of this patchset. I also have modifications in the works to ease transition, for example, but having a separate CONFIG_PROVE_RCU.
Please accept my apologies for the mislabeling!!!
Thanx, Paul
