The ATAPI: interface has no DMA at all
The ATA: fixes a DMA bug that should be ficed the same way for ide-scsi.
It is just annoing to see that the Linux kernel folks first
copied the code from ide-scsi just to create this unneeded new
interface and later onlu fixed the bug in the copy but not in the
original
