sata_mv: simplify request/response queue handling
Try and simplify handling of the request/response queues. Maintain the cached copies of queue indexes in a fully-masked state, rather than having each use of them have to do the masking. Split off handling of a single crpb response into a separate function, to reduce complexity in the main mv_process_crpb_entries() routine. Ignore the rarely-valid error bits from the crpb status field, as we already handle that information in mv_err_intr(). For now, preserve the rest of the original logic. A later patch will deal with fixing that separately. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
