The appropriate functionality of the callback is established through querying the ATAPI packet command in pc->c[0].

Log device name instead of driver name in *_pc_intr() and *_transfer_pc*().

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.

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).

This converts ide to use blk_rq_init to initialize the request. This is a preparation for large command support, which needs to initialize the request in a proper way (that is, just doing a memset() will not work).

* Add ide_pad_transfer() helper (which uses ->{in,out}put_data methods internally so the transfer is also padded to drive+host requirements) and use it instead of ide_atapi_{write_zeros,discard_data}(). * Remove no longer needed ide_atapi_{write_zeros,discard_data}().

* Merge ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods into new ->{in,out}put_data methods which take number of bytes to transfer as an argument and always do padding. While at it: * Use 'hwif' or 'drive->hwif' instead of 'HWIF(drive)'.

Instead of allocating pages for the buffer one by one, take advantage of the buddy alloc system and request them 2^order at a time. This increases the chance for bigger buffer parts to be contigious and reduces loop iteration count. While at it, rename function __idetape_kmalloc_stage() to ide_tape_kmalloc_buffer().
