A kernel convention for many allocators is that if __GFP_ZERO is passed to

This is currently not supported by the slab allocators. The inconsistency
makes it difficult to implement in derived allocators such as in the uncached
allocator and the pool allocators.

So add the necessary logic to all slab allocators to support __GFP_ZERO.

Looks good to me.
