Didn't see any. Only the dma_addr_t thing can be 32 bit or 64 bit depending on some magic. Apart this, the driver is asking for the appropriate dma mask given the configured dma adressing mode. G?rard. PS: There is some pci64* API on some arch., but nobody will want to ever use it, in my opinion. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
