* 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
(Noticed by Andrew Morton).

* 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.

PATA part of all current JMB controllers behave the same way and
JMicron confirms that all future ones will stay compatible. Matching
vendor and device class is enough.
For backward compatibility, jmicron still needs to match 361,3,5,6,8
DIDs regardless of device class if libata is not configured but won't

Switch to using pci_get_slot() in init_setup_pdc20270() to get to the mate chip

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...

SB700 supports one physical IDE channel, but SB700 SATA controller
supports combined mode. When the SATA combined mode is enabled,
two SATA ports (port4 and port5) share one IDE channel from IDE
controller, and PATA will share the other IDE channel.
Our previous patch adding SB700 IDE device ID only supports one
IDE channel, which contains bug. The attached patch fixes the bug.

Three main sets of changes:
1) dmi_get_system_info() return value should have been marked const,
since callers should not be changing that data.
2) const-ify DMI internals, since DMI firmware tables should,
whenever possible, be marked const to ensure we never ever write to
that data area.
3) const-ify DMI API, to enable marking tables const where possible
in low-level drivers.
And if we're really lucky, this might enable some additional
optimizations on the part of the compiler.
The bulk of the changes are #2 and #3, which are interrelated. #1 could
have been a separate patch, but it was so small compared to the others,
it was easier to roll it into this changeset.

The Marvell bridge chips used on HighPoint SATA cards do not seem to support
the UltraDMA modes 1, 2, and 3 as well as any MWDMA modes, so the driver needs
to account for this in the udma_filter() method. In order to achieve that, do
the following changes:
- install the method for all chips, not only HPT36x/370 and improve the code
formatting by killing the extra tabs while at it;
- add to the end of the 'switch' statement in the method cases for HPT372[AN]
and HPT374 chips upon which the known SATA cards are based;
- use hwif->ultra_mask as a default mask for the ide_dma_filter() method to
behave correctly;
- move the HPT370[A] cases below the HPT36x case for consistency.
While at it, replace the explicit UltraDMA mode masks with ATA_UDMA* constants
all over the driver...

HPT374 BIOS seems to only save f_CNT register value for the function #0 before
re-tuning DPLL (that causes the driver to report obviously distorted f_CNT for
the function #1) -- fix this by always reading the saved f_CNT register value
from the function #0 in the driver's init_chipset() method.

Programming DMA mode may destroy current PIO mode setting so if
CONFIG_HPT34X_AUTODMA=n (the default case) make ide_tune_dma() fail
early by disabling all host DMA masks and re-tune PIO mode.
