SLUB: remove useless masking of GFP_ZERO
Christoph Lameter [Tue, 18 Dec 2007 00:20:27 +0000 (16:20 -0800)]
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.
