powerpc: remove all rcu head initializations
Paul E. McKenney [Tue, 11 May 2010 00:01:30 +0000 (17:01 -0700)]
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.
