* ide: remove drive->ctlBartlomiej Zolnierkiewicz2008-07-151-5/+5
| | | | | | | | | | | | Remove drive->ctl (it is always equal to 0x08 after init time). While at it: * Use ATA_DEVCTL_OBS define. There should be no functional changes caused by this patch. Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* ide: move IRQ unmasking out from ->tf_load methodBartlomiej Zolnierkiewicz2008-07-151-4/+1
| | | | | | | | | 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>
* ide: remove IDE_TFLAG_NO_SELECT_MASK taskfile flagBartlomiej Zolnierkiewicz2008-07-151-3/+1
| | | | | | | | | | | | | 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).

* ide: disable drive interrupts in ide_driveid_update()Mikhail Cherkashin2008-07-151-1/+1
| | | | | | | | | | | | | | Since ide_driveid_update() uses polling to execute the IDENTIFY DEVICE command but clears nIEN bit in the control register and doesn't mask the IDE interrupt, the latter does happen and lead to the corresponding message to appear: ide0: unexpected interrupt, status=0x58, count=1 when e.g. running hdparm with option -X with a non-PCI IDE driver...

| | | | | | | | | | | | | | | * 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)'.

* falconide/q40ide: add ->atapi_*put_bytes and ->ata_*put_data methods (take 2)Bartlomiej Zolnierkiewicz2008-04-281-19/+7
| | | | | | | | | | | | | | | | | | | | | | | * Add ->atapi_{in,out}put_bytes and ->ata_{in,out}put_data methods to falconide and q40ide host drivers (->ata_* methods are implemented on top of ->atapi_* methods so they also do byte-swapping now). * Cleanup atapi_{in,out}put_bytes(). v2: * Add 'struct request *rq' argument to ->ata_{in,out}put_data methods and don't byte-swap disk fs requests (we shouldn't un-swap fs requests because fs itself is stored byte-swapped on the disk) - this is how things were done before the patch (ideally device mapper should be used instead but it would break existing setups and would have some performance impact).

| | | | | | | | | | | | | | | | | | | This reverts commit b140b99c413ce410197cfcd4014e757cd745226a. [ conflict in drivers/ide/ide-probe.c fixed manually ] It turned out that probing order change causes problems for some drives: http://bugzilla.kernel.org/show_bug.cgi?id=10239 Since root causes are still being investigated and are unlikely to be fixed before 2.6.25 lets revert this change for now. As a result cable detection becomes less reliable when compared with 2.6.24 but the affected drives are useable again.
