Paul ... what do you think? This is just an interim measure to get 
the build going - i think we could do more cleanups here perhaps, if 
you agree.

I think many of the data definitions (and the resulting include file 
dependencies) in include/linux/rcu*.h could move into kernel/rcu*.h 
and be privatized that way. 'struct rcu_state' would be an example.

Agreed?
