[PATCH] mm, slub: better heuristic for number of cpus when calculating slab order

When creating a new kmem cache, SLUB determines how large the slab pages will based on number of inputs, including the number of CPUs in the system. Larger slab pages mean that more objects can be allocated/free from per-cpu slabs before accessing shared structures, but also potentially more
