From: Huaisheng Ye <[email protected]> Use __GFP_ZONE_MASK to replace (__GFP_DMA | __GFP_HIGHMEM | __GFP_DMA32).
___GFP_DMA, ___GFP_HIGHMEM and ___GFP_DMA32 have been deleted from GFP bitmasks, the bottom three bits of GFP mask is reserved for storing encoded zone number. __GFP_DMA, __GFP_HIGHMEM and __GFP_DMA32 should not be operated with each others by OR.
