slab: Use common kmalloc_index/kmalloc_size functions
Make slab use the common functions. We can get rid of a lot of old ugly stuff as a results. Among them the sizes array and the weird include/linux/kmalloc_sizes file and some pretty bad #include statements in slab_def.h. The one thing that is different in slab is that the 32 byte cache will also be created for arches that have page sizes larger than 4K. There are numerous smaller allocations that SLOB and SLUB can handle better because of their support for smaller allocation sizes so lets keep the 32 byte slab also for arches with > 4K pages.
