kmalloc caches are statically defined and may take up a lot of space just because the sizes of the node array has to be dimensioned for the largest node count supported. This patch makes the size of the kmem_cache structure dynamic throughout by creating a kmem_cache slab cache for the kmem_cache objects. The bootstrap occurs by allocating the initial one or two kmem_cache objects from the page allocator. C2->C3 - Fix various issues indicated by David - Make create kmalloc_cache return a kmem_cache * pointer.
