Checking in gfp.h, I see:
#define __GFP_DMA 0x01
#define __GFP_HIGHMEM 0x02
#define __GFP_WAIT 0x10 /* Can wait and reschedule? */
#define __GFP_HIGH 0x20 /* Should access emergency pools? */
#define __GFP_IO 0x40 /* Can start physical IO? */
#define __GFP_FS 0x80 /* Can call down to low-level FS? */
#define GFP_KERNEL (__GFP_WAIT | __GFP_IO | __GFP_FS)
Thus, it looks like it's not a dma allocation. By my reading, it
appears to be a standard GFP_KERNEL.
