slub: Make the order configurable for each slab cache
Makes /sys/kernel/slab/<slabname>/order writable. The allocation order of a slab cache can then be changed dynamically during runtime. This can be used to override the objects per slabs value establisheed with the slub_min_objects setting that was manually specified or calculated on bootup. The changes of the slab order can occur while allocate_slab() runs. Allocate slab needs the order and the number of slab objects that are both changed by the change of order. Both are put into a single word (struct kmem_cache_order_objects). They can then be atomically updated and retrieved.
