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}.

v2:
* updated for scc_pata
Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* 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
Signed-off-by: NBartlomiej Zolnierkiewicz <bzolnier@gmail.com>

* remove redundant svwks_ide_dma_end() [ __ide_dma_end() is used by default ]
* remove init_dma_svwks() so the default ide_setup_dma() function is used
  [ init_setup_csb6() takes care of not initializing disabled channels ]

As we don't support hotplug we end up leaking an isa_dev reference which if
unload was ever added we would drop at the end of unloading.  This is fine
because we do genuinely need the isa_dev pointer until unload.

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 ??]

Move auto arrays to static (const).  Clean up using PCI_DEVICE in places,
remove unreachable junk and dead code.

Fix the serverworks cable detect logic (if ordering is wrong).  Backport
from libata.  Plenty of scope for more cleanup left.

BCM5785 (HT1000) is a Opteron Southbridge from Serverworks/Broadcom that
incorporates a single channel ATA100 IDE controller that is functionally
identical to the Serverworks CSB6 IDE controller.  This patch adds support
for the new PCI device ID and also the support for this controller.

You can't install the base kernel on a Stratus box because of the overuse of
__init.  Affects both IDE layers identically.  It isn't the only misuser of
__init so more review of other drivers (or fixing ide_register code to know
about hotplug v non-hotplug chipsets) would be good.

Original issue found by Stratus and their patch was the inspiration for this
trivial one.

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!
