Np. FYI, you'll want to use the latest commit e7827b351 HEAD from target-pending/scsi-mq, which now has functioning scsi-generic support.
Also, your scsi_times_out patch from earlier has not been included just yet, but that should be the only extra patch you need to apply in order to get scsi-mq enabled libata/ata_piix running.
