sata_mv new mv_qc_defer method The EDMA engine cannot tolerate a mix of NCQ/non-NCQ commands, and cannot be used for PIO at all. So we need to prevent libata from trying to feed us such mixtures. Introduce mv_qc_defer() for this purpose, and use it for all chip versions. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
