Subject: Memoryless Node: Slab support
From: Lee Schermerhorn <lee.schermerhorn@xxxxxx>
Slab should not allocate control structures for nodes without memory. This
may seem to work right now but its unreliable since not all allocations can
fall back due to the use of GFP_THISNODE.
Switching a few for_each_online_node's to for_each_memory_node will allow us
to only allocate for nodes that actually have memory.
