* hpt34x.c: disable DMA masks for HPT345
(hwif->autodma is zero so DMA won't be enabled anyway).* trm290.c: disable IDE_HFLAG_TRUST_BIOS_FOR_DMA flag
(hwif->autodma is zero so DMA won't be enabled anyway).* Check noautodma global variable instead of drive->autodma in ide_tune_dma().
This fixes handling of "ide=nodma" kernel parameter for icside, ide-cris,
au1xxx-ide, pmac, it821x, jmicron, sgiioc4 and siimage host drivers.* Remove hwif->autodma (it was not checked by IDE core code anyway) and
drive->autodma (was set by all host drivers - except HPT345/TRM290 special
cases - unless "ide=nodma" was used).While at it:
- remove needless printk() from icside.c
- remove stale FIXME/comment from ide-probe.c
- don't force DMA off if PCI bus-mastering had to be enabled in setup-pci.c
(this setting was always later over-ridden by host drivers anyway)Signed-off-by: Bartlomiej Zolnierkiewicz

While at it:
- make struct pci_device_id tables const
- use PCI_DEVICE_ID_ITE_8213 define in it8213.c
- fix comment in generic.cSigned-off-by: Bartlomiej Zolnierkiewicz

* Add IDE_HFLAG_TRUST_BIOS_FOR_DMA host flag for host drivers that depend
on BIOS for programming device/controller for DMA. Set it in cy82c693,
generic, ns87415, opti621 and trm290 host drivers.* Add IDE_HFLAG_VDMA host flag for host drivers using VDMA. Set it in cs5520
host driver.* Teach ide_tune_dma() about IDE_HFLAG_TRUST_BIOS_FOR_DMA flag.
* Add generic ide_dma_check() helper and remove all open coded ->ide_dma_check
implementations. Fix all places checking for presence of ->ide_dma_check
hook to check for ->ide_dma_on instead.* Remove no longer needed code from config_drive_for_dma().
* Make ide_tune_dma() static.
v2:
* Fix config_drive_for_dma() return values.* Fix ide-dma.c build for CONFIG_BLK_DEV_IDEDMA_PCI=n by adding
dummy config_drive_for_dma() inline.* Fix IDE_HFLAG_TRUST_BIOS_FOR_DMA handling in ide_dma_check().
* Fix init_hwif_it8213() comment.
There should be no functionality changes caused by this patch.

* 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).* Improve some ->set_pio_mode comments.

This results in smaller/faster/simpler code and allows future optimizations.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
