Plain GFP_DMA is really only appropriate when used for ISA DMA situations where we must have 24-bit addresses or whatever that restriction was. Anyways, it is dma_map_single()'s job to restrict DMA addressing if necessary. Otherwise, the transmit path would not work at all. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
