Hello!
Would you guys like to carry this patch, or should I push it up
-tip? If I don't hear otherwise from you, I will push it up -tip.
The INIT_RCU_HEAD() primitive is going away in favor of debugobjects.
Thanx, Paul

powerpc: remove all rcu head initializations
Remove all rcu head inits. We don't care about the RCU head state before
passing it to call_rcu() anyway. Only leave the "on_stack" variants so
debugobjects can keep track of objects on stack.
