There's no config named SLAB_DEBUG, and it should be a typo
of SLUB_DEBUG.

I don't see how, there should be no partial or full slabs for either 
kmem_cache or kmem_cache_node at this point in the boot sequence.  I think 
kmem_cache_bootstrap_fixup() should only need to add the cache to the list 
of slab caches and set the refcount accordingly.

Hmmm... That depends on the number of objects in a slab page. If that is
one then we may have an issue.
