[PATCH] Slab: Do not fallback to nodes that have not been bootstrapped yet  
  
The zonelist may contain zones of nodes that have not been bootstrapped and  
we will oops if we try to allocate from those zones. So check if the node  
information for the slab and the node have been setup before attempting an  
allocation. If it has not been setup then skip that zone.  
  
Usually we will not encounter this situation since the slab bootstrap code  
avoids falling back before we have setup the respective nodes but we seem  
to have a special needs for pppc.
