SubjectProposal: Eliminate GFP_DMA

I'm thinking about doing something along these lines:

--- linux-2.5.63/include/linux/gfp.h 2003-02-24 13:05:13.000000000 -0600
+++ linux-2.5.63-gfpdma/include/linux/gfp.h 2003-02-27 17:24:39.000000000 -0600
@@ -26,11 +26,8 @@

-/* Flag - indicates that the buffer will be suitable for DMA. Ignored on some
- platforms, used as appropriate on others */
-
-#define GFP_DMA __GFP_DMA
-
+#define GFP_ATOMIC_DMA (GFP_ATOMIC | __GFP_DMA)
+#define GFP_KERNEL_DMA (GFP_KERNEL | __GFP_DMA)

combined with changing some users to use __GFP_DMA if they really do mean
the bitmask. Comments?
