Add PC_FLAG_DRQ_INTERRUPT pc flag, set it in ide*_do_request()
and check for it (instead of checking for IDE*_FLAG_DRQ_INTERRUPT)
in ide*_issue_pc(). This is a preparation for adding generic
ide_issue_pc() helper.
There should be no functional changes caused by this patch.
Add PC_FLAG_ZIP_DRIVE pc flag, set it in idefloppy_do_request()
and check for it (instead of checking for IDEFLOPPY_FLAG_ZIP_DRIVE)
in idefloppy_transfer_pc(). This is a preparation for adding

ide-tape: factor out waiting for good ireason from idetape_transfer_pc()
Factor out waiting for good ireason from idetape_transfer_pc()
to ide_tape_wait_ireason() as a preparation for adding generic
ide_transfer_pc() helper.

ide-floppy: start DMA engine in idefloppy_transfer_pc1()
Start DMA engine and set PC_FLAG_DMA_IN_PROGRESS flag in
idefloppy_transfer_pc1() instead of idefloppy_issue_pc()
so the Status Register and the Interrupt Reason Register
are checked first.
ide-scsi: fix handling of DMA errors in idescsi_pc_intr()
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.
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.
ide-scsi: replace ide_do_drive_cmd with blk_execute_rq_nowait
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.
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.
ide: remove IDE_TFLAG_NO_SELECT_MASK taskfile flag
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).

block: remove the checking for NULL queue in blk_put_request
Some uses blk_put_request asymmetrically, that is, they uses it with
requests that not allocated by blk_get_request. As a result,
blk_put_request has a hack to catch a NULL request_queue. Now such
callers are fixed (they use blk_get_request properly). So we can
safely remove the hack in blk_put_request.
block: convert pd_special_command to use blk_execute_rq
pd_special_command uses blk_put_request with struct request on the
stack. As a result, blk_put_request needs a hack to catch a NULL
request_queue. This converts pd_special_command to use
blk_execute_rq.
ide_cd_init_rq is not used by ide-cd_ioctl any more. Only
cdrom_queue_request_sense use it. This converts
cdrom_queue_request_sense to use blk_rq_init directly and removes
ide_cd_init_rq.
ide: remove ide_wait/head_wait path in ide_do_drive_cmd
Now all the users of ide_do_drive_cmd using ide_wait/head_wait are
converted to use blk_execute_rq this removes the ide_wait/head_wait
path in ide_do_drive_cmd.
