Just a few cleanups to use zalloc style calls and reduce
the uses of __GFP_ZERO for kmem_cache_alloc[_node] uses.
Use the more kernel normal zalloc style.
Joe Perches (6):
slab/block: Add and use kmem_cache_zalloc_node
block: Convert kmem_cache_alloc(...GFP_ZERO) to kmem_cache_zalloc
i915_g
The helper exists, might as well use it instead of __GFP_ZERO.
