3608b5d71a ide: add ide_set_dma() helper (v2)
* add ide_set_dma() helper and make ide_hwif_t.ide_dma_check return
  -1 when DMA needs to be disabled (== need to call ->ide_dma_off_quietly)
   0 when DMA needs to be enabled  (== need to call ->ide_dma_on)
   1 when DMA setting shouldn't be changed
* fix IDE code to use ide_set_dma() instead if using ->ide_dma_check directly

v2:
* updated for scc_pata

0ecdca26e5 ide: use PIO/MMIO operations directly where possible (v2)
This results in smaller/faster/simpler code and allows future optimizations.
Also remove no longer needed ide[_mm]_{inl,outl}() and ide_hwif_t.{INL,OUTL}.

7569e8dc22 ide: add ide_use_fast_pio() helper (v3)
* add ide_use_fast_pio() helper for use by host drivers

* add DMA capability and hwif->autodma checks to ide_use_dma()

  - au1xxx-ide/it8213/it821x drivers didn't check for (id->capability & 1)

    [ for the IT8211/2 in SMART mode this check shouldn't be made but since
      in it821x_fixups() we set DMA bit explicitly:

               if(strstr(id->model, "Integrated Technology Express")) {
                       /* In raid mode the ident block is slightly buggy
                          We need to set the bits so that the IDE layer knows
                          LBA28. LBA48 and DMA ar valid */
                       id->capability |= 3;            /* LBA28, DMA */

       we are better off using generic helper if we can ]

  - ide-cris driver didn't set ->autodma

    [ before the patch hwif->autodma was only checked in the chipset specific
      hwif->ide_dma_check implementations, for ide-cris it is cris_dma_check()
      function so there no behavior change here ]

v2:
* updated patch description (thanks to Alan Cox for the feedback)

v3:
* updated for scc_pata driver

056a697b73 ide: unexport ide_set_xfer_rate() (v2)
In cmd64x, siimage and scc_pata drivers:
* don't set drive->init_speed as it should be already
  set by successful execution of ide_set_xfer_rate()
* use hwif->speedproc functions directly

Above changes allows removal of EXPORT_SYMBOL_GPL(ide_set_xfer_rate).

v2:
* updated for scc_pata driver

075cb65511 siimage: PIO1/2 taskfile transfer overclocking fix
Fix two typos found by SiI680A documentation check.  They caused the taskfile
transfer overclocking:

- in PIO mode 1 as 0x2283 must be used for both data and taskfile transfers;

- in PIO mode 2 as data and taskfile timings are swapped when writing to the
  MMIO regs.

Fix coding style and trailing whitespace in enclosing statements while at it...

28a2a3f587 [PATCH] Fix 2.6.18-rc6 IDE breakage, add missing ident needed for current VIA boards
There are two changes here.  The first reverses the broken PCI_DEVICE
conversion back to the old format.  The second adds a missing PCI ID so
you can actually boot 2.6.18 on 2 month old VIA motherboards (right now
only 2.6.18-mm works).

CC'd to Jeff to check the PCI ident but its a) in several distro kernels
and b) in 2.6.18-mm [twice ??]

19c1ef5f67 [PATCH] ide: clean up siimage
Remove all the ifdef preparation for enhanced features that never occcurred
and is only in libata.  For the SATA chips (but not yet PATA ones) politely
suggest to the user that libata may offer more features.

d868dd19ad [PATCH] siimage: enable interrupts on Adaptec SA-1210 card
The siimage driver proports to support the Adaptec SA-1210 SATA
controller.  However, at least some of those cards boot-up with their
interrupts disabled internally.  The siimage driver currently ignores
that fact, so that driver does not actually work with those cards.
This patch enables those interrupts on cards that need it.

[ This is implemented based on similar code in the libata-based
  sata_sil driver. ]

1da177e4c3 Linux-2.6.12-rc2
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!
