Bartlomiej Zolnierkiewicz fcc1175947 ide: remove BUG_ON() from ide_build_sglist()
do_rw_taskfile() has been fixed to check the return value
of ->dma_setup method so this BUG_ON() is no longer needed.

Bartlomiej Zolnierkiewicz 425afb6103 ide: fix ide_intr() for non-PCI devices and CONFIG_BLK_DEV_IDEPCI=y
'hwif->pci_dev && !hwif->pci_dev->vendor' condition is never true,
check for 'hwif->chipset != ide_pci' instead.

Bartlomiej Zolnierkiewicz 4166c1993b ide: add IDE_HFLAG_NO_DSC host flag
* Add IDE_HFLAG_NO_DSC host flag for hosts that doesn't support DSC overlap.

* Set it in aec62xx (for ATP850UF only) and hpt34x host drivers.

* Convert ide-tape device driver to check for IDE_HFLAG_NO_DSC flag.

Bartlomiej Zolnierkiewicz 8ac2b42a45 ide: add IDE_HFLAG_CLEAR_SIMPLEX host flag
* Rename 'simplex_stat' variable to 'dma_stat' in ide_get_or_set_dma_base().

* Factor out code for forcing host out of "simplex" mode from
  ide_get_or_set_dma_base() to ide_pci_clear_simplex() helper.

* Add IDE_HFLAG_CLEAR_SIMPLEX host flag and set it in alim15x3 (for M5229),
  amd74xx (for AMD 7409), cmd64x (for CMD643), generic (for Netcell) and
  serverworks (for CSB5) host drivers.

* Make ide_get_or_set_dma_base() test for IDE_HFLAG_CLEAR_SIMPLEX host flag
  instead of checking dev->device (BTW the code was buggy because it didn't
  check for dev->vendor, luckily none of these PCI Device IDs was used by
  some other vendor for PCI IDE controller).

Bartlomiej Zolnierkiewicz 993da8f9ea amd74xx: remove amd_ide_chips table
* Remove no longer needed assertion from amd74xx_probe().

* Factor out cable detection for AMD7409 to amd7409_cable_detect() and for
  chipsets >= AMD7411 to amd7411_cable_detect().

* Use dev->vendor and dev->device instead of amd_config->udma_mask when
  selecting cable detection method and checking for broken FIFO support in
  init_chipset_amd74xx().

* Remove no longer needed AMD_BAD_FIFO define.

* Add 'swdma' parameter for setting .swdma_mask to DECLARE_AMD_DEV() macro.

* Add 'udma' parameter for setting .udma_mask to DECLARE_{AMD,NV}_DEV() macro.

* Keep a copy of a current amd74xx_chipsets[] entry in amd74xx_probe()
  in order to fix ->swdma_mask on early AMD7409 revisions and ->udma_mask
  on Serenade mainboards.

* Remove no longer needed fixups from init_chipset_amd74xx()
  and AMD_CHECK_{SWDMA,SERENADE} defines.

* Move printing banner message from init_chipset_amd74xx() to amd74xx_probe(),
  also remove incorrect comment while at it.

* Use hwif->ultra_mask instead of amd_config->udma_mask in amd_set_drive().

* Add 'udma_mask' argument to amd_set_speed() and pass UDMA mask from
  amd_set_drive() instead of using amd_config->udma_mask.

* Move amd_config->base from AMD_* defines to users of these defines and add
  0x40 the defined values.  Then add amd_offset() inline helper for selecting
  offset from 0x40 base (needed for nVidia controllers) and finally use it in
  amd_set_speed(), amd7411_cable_detect() and init_chipset_amd74xx() instead
  of amd_config->base.

* Remove no longer needed AMD_BAD_SWDMA define, ->{swdma,ultra}_mask setup
  from init_hwif_amd74xx(), amd_{config,chipset} variables and amd_ide_chips
  table.

* Fix init_chipset_amd74xx() comment.

* Bump driver version.

There should be no functionality changes caused by this patch.

Sergei Shtylyov ecf3279639 ide: ide_setup_dma() assumes 8 ports
According to http://marc.info/?l=linux-ide&m=114346138611631, the drivers must
always register 8 DMA ports with ide_setup_dma(), so its last argument is not
needed. While at it, kill some useless parens in that function...
