Patch from Steven Scholz:
should we rename the define into CONFIG_FEATURE_HDPARM_HDIO_DMA and use it for "set" and "get" ??? Since although CONFIG_FEATURE_HDPARM_HDIO_GET_DMA is _not_ set I still can use "hdparm -d 1 /dev/hda" to switch the DMA on. Is this desireable or meant to be like that? So how about the applied patch?
