2008-07-15ide-floppy: merge idefloppy_transfer_pc() and idefloppy_transfer_pc1()Bartlomiej Zolnierkiewicz
* Check IDEFLOPPY_FLAG_ZIP_DRIVE flag in idefloppy_transfer_pc1() and skip idefloppy_transfer_pc2()-phase if the flag is not set. * Always use idefloppy_transfer_pc1() in idefloppy_issue_pc() and remove no longer needed idefloppy_transfer_pc(). There should be no functional changes caused by this patch. Cc: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

2008-07-15ide-scsi: add debug_log() macroBartlomiej Zolnierkiewicz
Add debug_log() macro and convert the driver to use it. [ This makes debug messages to be always prefixed with "ide-scsi: " and use KERN_INFO level. ] While at it: * Change "DMA complete" debug message to "DMA finished" to match other ATAPI device drivers. * Use __func__.

2008-07-15ide-scsi: remove superfluous BUG_ON() from idescsi_transfer_pc()Bartlomiej Zolnierkiewicz

2008-07-15ide-scsi: fix handling of DMA errors in idescsi_pc_intr()Bartlomiej Zolnierkiewicz
Check return value of ->dma_end method and if there was a DMA error handle it accordingly (set PC_FLAG_DMA_ERROR pc flag, don't update pc->xferred and increase rq->errors). Also move debug message in the right place while at it. Cc: Borislav Petkov <petkovbb@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-07-15ide-scsi: fix DRQ checking for DMA transfers in idescsi_pc_intr()Bartlomiej Zolnierkiewicz

2008-07-15ide-scsi: fix race in idescsi_transfer_pc()Bartlomiej Zolnierkiewicz

2008-07-15ide: remove action argument in ide_do_drive_cmdFUJITA Tomonori
ide_do_drive_cmd is called only with ide_preempt action argument. So we can remove the action argument in ide_do_drive_cmd and ide_action_t typedef. This patch also includes two minor cleanups: 1) ide_do_drive_cmd always succeeds so we don't need the return value; 2) the callers use blk_rq_init before ide_do_drive_cmd so there is no need to initialize rq->errors.

2008-07-15ide-scsi: replace ide_do_drive_cmd with blk_execute_rq_nowaitFUJITA Tomonori
All the callers of ide_do_drive_cmd() except for ide-scsi use ide_preempt action argument. This converts ide-scsi to use blk_execute_rq_nowait instead of ide_do_drive_cmd so that we can remove the action argument in ide_do_drive_cmd and ide_action_t typedef.

2008-07-15ide: remove ->mmio flag from ide_hwif_tBartlomiej Zolnierkiewicz
Since scc_pata host driver no longer uses IDE PCI layer / ide_dma_setup() and all other ->mmio users set also IDE_HFLAG_MMIO host flag we can safely remove ->mmio flag. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-07-15ide: move IRQ unmasking out from ->tf_load methodBartlomiej Zolnierkiewicz
Move IRQ unmasking out from ->tf_load method to its users. There should be no functional changes caused by this patch (SELECT_MASK() is NOP except for hpt366, icside and sgiioc4). Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
2008-07-15ide: remove IDE_TFLAG_NO_SELECT_MASK taskfile flagBartlomiej Zolnierkiewicz
Always call SELECT_MASK(..., 0) in ide_tf_load() (needs to be done to match ide_set_irq(..., 1)) and then remove IDE_TFLAG_NO_SELECT_MASK taskfile flag. This change should only affect hpt366 and icside host drivers since ->maskproc(..., 0) for sgiioc4 is equivalent to ide_set_irq(..., 1).

2008-07-15block: convert pd_special_command to use blk_execute_rqFUJITA Tomonori
