* Filter out "default" transfer mode values (0x00 - default PIO mode,
0x01 - default PIO mode w/ IORDY disabled) in write handler for obsoleted
/proc/ide/hd?/settings:current_speed setting.
Allowing "default" transfer mode values is a dangerous thing to do as
we don't support programming controller to the "default" transfer mode
and devices often use different values for the default and maximum PIO
mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay
programmed for higher PIO mode while device will use the lower PIO mode.
There is no functionality loss as by using special IOCTLs device can
still be programmed to "default" transfer modes (it is only useful for
debugging/testing purposes anyway).
* Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was

timings for "default" transfer mode == 0x01 (although some host drivers

hdparm explicitely marks HDIO_[UNREGISTER,SCAN]_HWIF ioctls as DANGEROUS
and given the number of bugs we can assume that there are no real users:
* DMA has no chance of working because DMA resources are released by
ide_unregister() and they are never allocated again.
* Since ide_init_hwif_ports() is used for ->io_ports[] setup the ioctls
don't work for almost all hosts with "non-standard" (== non ISA-like)
layout of IDE taskfile registers (there is a lot of such host drivers).
* ide_port_init_devices() is not called when probing IDE devices so:
- drive->autotune is never set and IDE host/devices are not programmed
for the correct PIO/DMA transfer modes (=> possible data corruption)
- host specific I/O 32-bit and IRQ unmasking settings are not applied
(=> possible data corruption)
- host specific ->port_init_devs method is not called (=> no luck with
ht6560b, qd65xx and opti621 host drivers)
* ->rw_disk method is not preserved (=> no HPT3xxN chipsets support).
* ->serialized flag is not preserved (=> possible data corruption when
using icside, aec62xx (ATP850UF chipset), cmd640, cs5530, hpt366
(HPT3xxN chipsets), rz1000, sc1200, dtc2278 and ht6560b host drivers).
* ->ack_intr method is not preserved (=> needed by ide-cris, buddha,
gayle and macide host drivers).
* ->sata_scr[] and sata_misc[] is cleared by ide_unregister() and it
isn't initialized again (SiI3112 support needs them).
* To issue an ioctl() there need to be at least one IDE device present
in the system.
* ->cable_detect method is not preserved + it is not called when probing
IDE devices so cable detection is broken (however since DMA support is
also broken it doesn't really matter ;-).
* Some objects which may have already been freed in ide_unregister()
are restored by ide_hwif_restore() (i.e. ->hwgroup).
* ide_register_hw() may unregister unrelated IDE ports if free ide_hwifs[]
slot cannot be found.
* When IDE host drivers are modular unregistered port may be re-used by
different host driver that owned it first causing subtle bugs.
Since we now have a proper warm-plug support remove these ioctls,
then remove no longer needed:
- ide_register_hw() and ide_hwif_restore() functions
- 'init_default' and 'restore' arguments of ide_unregister()
- zeroeing of hwif->{dma,extra}_* fields in ide_unregister()

ide: switch idedisk_prepare_flush() to use REQ_TYPE_ATA_TASKFILE requests
...
broke flush requests.
Allocating IDE command structure on the stack for flush requests is not
a very brilliant idea:
- idedisk_prepare_flush() only prepares the request and it doesn't wait
for it to be completed
- there are can be multiple flush requests queued in the queue
Fix the problem (per hints from James Bottomley) by:
- dynamically allocating ide_task_t instance using kmalloc(..., GFP_ATOMIC)
- adding new taskfile flag (IDE_TFLAG_DYN)
- calling kfree() in ide_end_drive_command() if IDE_TFLAG_DYN is set
(while at it rename 'args' to 'task' and fix whitespace damage)
[ This will be fixed properly before 2.6.25 but this bug is rather
critical and the proper solution requires some more work + testing. ]

problem and testing patches (extra thanks to Sebastian for bisecting

In ide_taskfile_ioctl(), there was a race condition involving
drive->io_32bit. It was cleared and restored during ioctl
requests but there was no synchronization with other requests.
So, other requests could execute with the altered ->io_32bit
setting or updated drive->io_32bit could be overwritten by
ide_taskfile_ioctl().
This patch adds IDE_TFLAG_IO_16BIT flag to indicate to
ide_pio_datablock() that 16-bit I/O is needed regardless of
drive->io_32bit settting.

Remove broken disk byte-swapping support:
- it can cause a data corruption on SMP (or if using PREEMPT on UP)
- all data coming from disk are byte-swapped by taskfile_*_data() which
results in incorrect identify data being reported by /proc/ide/ and IOCTLs
- "hdx=bswap/byteswap" kernel parameter has been broken on m68k host drivers
(including Atari/Q40 ones) since 2.5.x days (because of 'hwif' zero-ing)
- byte-swapping is limited to PIO transfers (for working with TiVo disks on
x86 machines using user-space solutions or dm-byteswap should result in
much better performance because DMA can be used)

Given that:
* hpt366.c::hpt3xx_intrproc() is the only user of hwif->intrproc
* hpt366.c::hpt3xx_quirkproc() sets drive->quirk_list to 1 for quirky drives
which is a value unique to hpt366 host driver
we can remove hwif->intproc and just check for drive->quirk_list == 1

hdd: ATAPI 48X DVD-ROM DVD-R-RAM CD-R/RW drive, 2048kB Cache<7>hdd:

printk( ... "2048kB Cache");
eighty_ninty_three()
printk(KERN_DEBUG "%s: skipping word 93 validity check\n");
ide_dma_verbose()
printk(", UDMA(66)"
Please note that as a result ide-{cd,disk} device drivers won't report the
DMA speed used but this is intended since now DMA mode being used is always
reported by IDE core code.
v2:

Use ide_config_drive_speed() instead of pmac_ide_do_setfeature() and remove
the latter, also ide-iops.c::__ide_wait_stat() could be static again.
Since for IDE PMAC host driver IDE_CONTROL_REG is always true, device's
->quirk_list is always zero and ->ide_dma_host_{on,off} are nops than
the only changes in behavior are:
* if PIO mode is set then ->dma_off_queitly is called to disable DMA
* if setting transfer mode fails ide_dump_status() is called to dump status
v2:
* IDE PMAC controllers allow separate PIO and DMA timings and PPC userland
depends on this fact, and calls "hdparm -p" without calling "hdparm -d".
Therefore to compensate for DMA being disabled by ide_config_drive_speed()
for PIO modes:
- add IDE_HFLAG_SET_PIO_MODE_KEEP_DMA flag and set it in PMAC host driver
- add handling of the new flag to ide-io.c::do_special()

* Use __ide_wait_stat() instead of wait_for_ready() in pmac_ide_do_setfeature().
While at it do following changes to match __ide_wait_stat() call in
ide_config_drive_speed():
* Wait WAIT_CMD time (20 sec) instead of 2 sec for device to clear BUSY_STAT.
* Check DRQ_STAT bit (shouldn't be set for good device status).
Also remove no longer needed wait_for_ready() from ide-iops.c.

* Split off checking of the status register from ide_wait_stat() to
__ide_wait_stat() helper.
* Use the new helper in ide_config_drive_speed(). The only change in the
functionality is that the function now fails if after 20 sec (WAIT_CMD)
device is still busy (BUSY_STAT bit is set) while previously instead of
failing the function continued with checking for the correct device status
(which would give the device additional 10 usec to clear BUSY_STAT bit).
* Remove stale comment for ide_config_drive_speed().
* Remove duplicate comment for ide_wait_stat() from <linux/ide.h>.

* Add IDE_HFLAG_ABUSE_{PREFETCH,FAST_DEVSEL,DMA_MODES} flags
and set them in ht6560, cmd640, cmd64x and sc1200 host drivers.
* Add set_pio_mode_abuse() for checking if host driver has a non-standard
->tuneproc() implementation and use it in do_special().
* Add ide_set_pio() for setting PIO mode (it uses hwif->pio_mask to find
the maximum PIO mode supported by the host), also add ide_set_max_pio()
wrapper for ide_set_pio() to use for auto-tuning. Convert users of
->tuneproc to use ide_set{_max}_pio() where possible. This leaves only
do_special(), set_using_pio(), ide_hwif_restore() and ide_set_pio() as
a direct users of ->tuneproc.
* Remove no longer needed ide_get_best_pio_mode() calls and printk-s
reporting PIO mode selected from ->tuneproc implementations.
* Rename ->tuneproc hook to ->set_pio_mode and make 'pio' argument const.
* Remove stale comment from ide_config_drive_speed().
v2:
* Fix "ata_" prefix (Noticed by Jeff).
v3:
* Minor cleanups/fixups per Sergei's suggestions.
v4:
* Fix compile problem in drivers/ide/pci/cmd640.c

* Add an extra argument to ide_max_dma_mode() for passing requested transfer
mode. Use it as an upper limit when finding the best DMA for device/host.
* Rename ide_max_dma_mode() to ide_find_dma_mode() and at the same time add
ide_max_dma_mode() wrapper which passes XFER_UDMA_6 as a requested mode to
ide_find_dma_mode(). Also add inline ide_find_dma_mode() version for
CONFIG_BLK_DEV_IDEDMA=n case.
* Pass requested transfer mode from ide_find_dma_mode() to ide_get_mode_mask()
to avoid false warning from eighty_ninty_three().
* Use ide_find_dma_mode() to limit the user requested transfer mode in
ide_rate_filter(). Also limit the requested mode by host max PIO mode.
Above changes make ide_rate_filter() to:
* Clip desired transfer mode down if it is invalid (values 0x0F, 0x13-0x19
and 0x25-0x39, values > 0x46 were already clipped down, same for values
0x25-0x39 but iff UDMA was not supported by the host).
* Clip desired transfer mode down if it is currently unsupported by IDE core
(PIO6 and MWDMA3-4, the latter were already clipped down but iff UDMA was
not supported by the host).
* Clip desired transfer mode down according to the host capabilities
(UDMA modes were already clipped down but MWDMA/SWDMA/PIO weren't,
also ->atapi_dma flag was not respected).
* Clip desired transfer mode down according to the device capabilities
(except PIO modes for now which require mode work) - shouldn't be a
problem since ide_set_xfer_rate() is called _after_ device has accepted
given transfer mode.

ACPI spec defines the sequence of IDE power on/off:
Powering down:
Call _GTM.
Power down drive (calls _PS3 method and turns off power planes).
Powering up:
Power up drive (calls _PS0 method if present and turns on power planes).
Call _STM passing info from _GTM (possibly modified), with ID data from
each drive.
Initialize the channel.
May modify the results of _GTF.
For each drive:
Call _GTF.
Execute task file (possibly modified).
This patch adds the missed _PS0/_PS3 methods call.

The Marvell bridge chips used on HighPoint SATA cards do not seem to support
the MWDMA modes (at least that could be seen in their so-called drivers :-),
so the driver needs to account for this -- to achieve this:
- add mdma_filter() method from the original patch by Bartlomiej Zolnierkiewicz
with his consent;
- install the method for all chips to only return empty mask if a SATA drive
is detected on HPT372{AN]/374 chips...
