Now we have IS_ENABLED helper to check if a Kconfig option is enabled or not, so ZONE_DMA_FLAG sounds no longer useful.

And, the use of ZONE_DMA_FLAG in slab looks pointless according to the comment [1] from Johannes Weiner, so remove them and ORing passed in flags with the cache gfp flags has been done in kmem_getpages().

I haven't checked the patch but I have a formal suggestion. lkml.org tends to break and forget, please use http://lkml.kernel.org/r/%24msg-id instead. In this case http://lkml.kernel.org/r/20140925185047.GA21089@cmpxchg.org

Thanks!
