slab: introduce slab_max_order kernel parameter
Introduce new slab_max_order kernel parameter which is the equivalent of slub_max_order. For immediate purposes, allows users to override the heuristic that sets the max order to 1 by default if they have more than 32MB of RAM. This may result in page allocation failures if there is substantial fragmentation. Another usecase would be to increase the max order for better performance.
