Subject: SLUB: remove useless masking of GFP_ZERO
From: Christoph Lameter <clameter@xxxxxxx>
Remove a recently added useless masking of GFP_ZERO. GFP_ZERO is already
masked out in new_slab() (See how it calls allocate_slab). No need to do
it twice. This reverts the SLUB parts of
7fd272550bd43cc1d7289ef0ab2fa50de137e767.
