Memoryless nodes: Slab support

Browse source

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 N_NORMAL_MEMORY will allow us to
only allocate for nodes that have regular memory.
