* git://git.kernel.org/pub/scm/linux/kernel/git/bart/ide-2.6: (80 commits) ide-floppy: fix unfortunate function naming ide-tape: unify idetape_create_read/write_cmd ide: add ide_pc_intr() helper ide-{floppy,scsi}: read Status Register before stopping DMA engine ide-scsi: add more debugging to idescsi_pc_intr() ide-scsi: use pc->callback ide-floppy: add more debugging to idefloppy_pc_intr() ide-tape: always log debug info in idetape_pc_intr() if debugging is enabled ide-tape: add ide_tape_io_buffers() helper ide-tape: factor out DSC handling from idetape_pc_intr() ide-{floppy,tape}: move checking of ->failed_pc to ->callback ide: add ide_issue_pc() helper ide: add PC_FLAG_DRQ_INTERRUPT pc flag ide-scsi: move idescsi_map_sg() call out from idescsi_issue_pc() ide: add ide_transfer_pc() helper ide-scsi: set drive->scsi flag for devices handled by the driver ide-{cd,floppy,tape}: remove checking for drive->scsi ide: add PC_FLAG_ZIP_DRIVE pc flag ide-tape: factor out waiting for good ireason from idetape_transfer_pc() ide-tape: set PC_FLAG_DMA_IN_PROGRESS flag in idetape_transfer_pc() ...
