I would expect this patch to fix your issues. This will allow fallback
allocations to occur in the page allocator during slab bootstrap. This
means your per node queues will be contaminated as they were before. After
the slab allocator is fully booted then the per node queues will become
gradually become node clean.
I think it would be better if the PPC arch would fix this issue
by either making memory available on node 0 or setting up node 1 as
the boot node.
