Revert "SLUB: remove useless masking of GFP_ZERO"
This reverts commit 3811dbf67162bd08412f1b0e02e554f353e93bdb. The masking was not at all useless, and it was sensible. We handle GFP_ZERO in the caller, and passing it down to any page allocator logic is buggy and wrong. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
