Subject: ide: merge ide_match_hwif() and ide_find_port()

* Change ide_match_hwif() argument from 'u8 bootable' to
  'struct ide_port_info *d'.

* Move ide_match_hwif() to ide-probe.c from setup-pci.c and rename
  it to ide_find_port_slot().  Update some comments while at it.

* ide_find_port() can be now just a wrapper for ide_find_port_slot().

There should be no functional changes caused by this patch.

All host drivers now either set hwif->mmio or reserve continuous
I/O resources so remove no longer needed hwif->straight8 flag
and never reached code for 'hwif->straight8 == 0' case.

Subject: ide: add struct ide_port_ops (take 2)

* Move hooks for port/host specific methods from ide_hwif_t to
  'struct ide_port_ops'.

* Add 'const struct ide_port_ops *port_ops' to 'struct ide_port_info'
  and ide_hwif_t.

* Update host drivers and core code accordingly.

While at it:

* Rename ata66_*() cable detect functions to *_cable_detect() to match
  the standard naming. (Suggested by Sergei Shtylyov)

v2:
* Fix build for bast-ide. (Noticed by Andrew Morton)

Subject: ide: remove ->noprobe field from ide_hwif_t

Update IDE PMAC host driver to use drive->noprobe instead of hwif->noprobe
and remove hwif->noprobe completely (it is always set to zero now).

There should be no functional changes caused by this patch.

Subject: ide: remove ide_hwif_release_regions()

All host drivers using ide_unregister()/module_exit() have been fixed
to manage resources themselves so this function can be removed now.

There should be no functional changes caused by this patch.

Subject: ide: manage resources for PCI devices in ide_pci_enable() (take 3)

* Reserve PCI BARs 0-3 (0-1 for single port controllers) in
  ide_pci_enable() and remove ide_hwif_request_regions() call
  from ide_device_add_all() (also cleanup resource management
  in scc_pata host driver).

* Fix handling of PCI BAR 4 in ide_pci_enable(), then cleanup
  ide_iomio_dma() (+ init_hwif_trm290() in trm290 host driver)
  and remove ide_release[_iomio]_dma().

v2:
* Fixup trm290 host driver.

v3:
* Because of scc_pata host driver changes we need to call
  pci_request_selected_regions() also in setup_mmio_scc().

Subject: ide: add struct ide_dma_ops (take 3)

Add struct ide_dma_ops and convert core code + drivers to use it.

While at it:

* Drop "ide_" prefix from ->ide_dma_end and ->ide_dma_test_irq methods.

* Drop "ide_" "infixes" from DMA methods.

* au1xxx-ide.c:
  - use auide_dma_{test_irq,end}() directly in auide_dma_timeout()

* pdc202xx_old.c:
  - drop "old_" "infixes" from DMA methods

* siimage.c:
  - add siimage_dma_test_irq() helper
  - print SATA warning in siimage_init_one()

* Remove no longer needed ->init_hwif implementations.

v2:
* Changes based on review from Sergei:
  - s/siimage_ide_dma_test_irq/siimage_dma_test_irq/
  - s/drive->hwif/hwif/ in idefloppy_pc_intr().
  - fix patch description w.r.t. au1xxx-ide changes
  - fix au1xxx-ide build
  - fix naming for cmd64*_dma_ops
  - drop "ide_" and "old_" infixes
  - s/hpt3xxx_dma_ops/hpt37x_dma_ops/
  - s/hpt370x_dma_ops/hpt370_dma_ops/
  - use correct DMA ops for HPT302/N, HPT371/N and HPT374
  - s/it821x_smart_dma_ops/it821x_pass_through_dma_ops/

v3:
* Two bugs slipped in v2 (noticed by Sergei):
  - use correct DMA ops for HPT374 (for real this time)
  - handle HPT370/HPT370A properly

Subject: ide: add "ignore_cable" parameter (take 2)

Add "ignore_cable" parameter:

* "ide_core.ignore_cable=[interface_number]" boot option if IDE is built-in
  (i.e. "ide_core.ignore_cable=1" to force ignoring cable for "ide1")

* "ignore_cable=[interface_number]" module parameter (for ide_core module)
  if IDE is compiled as module

v2:
* Add ide_port_apply_params() helper
  - use it in ide_device_add_all() and ide_scan_port().

* Make it possible to later disable ignoring cable detection by passing
  "[interface_number]:0" to /sys/module/ide_core/parameters/ignore_cable
  (however sysfs interface is not enabled yet since it needs some other
   IDE changes to make it work reliable).

Subject: ide: remove obsoleted "hdx=noautotune" kernel parameter

Remove obsoleted "hdx=noautotune" kernel parameter
(it has been obsoleted since 1 Nov 2004).

Then make ide_hwif_t.autotune a single bit flag
and remove no longer needed IDE_TUNE_* defines.

* Remove needless hwif->chipset assignment from scc_pata.c::scc_remove().

v2:
* Fixup ide_unregister() documentation.

From 4c3032d8a4d6c97bd6e02bcab524ef2428d89561 Mon Sep 17 00:00:00 2001
From: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Date: Sun, 27 Apr 2008 15:38:32 +0200
Subject: ide: add struct ide_io_ports (take 3)

* Add struct ide_io_ports and use it instead of `unsigned long io_ports[]`
  in ide_hwif_t.

* Rename io_ports[] in hw_regs_t to io_ports_array[].

* Use un-named union for 'unsigned long io_ports_array[]' and 'struct
  ide_io_ports io_ports' in hw_regs_t.

* Remove IDE_*_OFFSET defines.

v2:
* scc_pata.c build fix from Stephen Rothwell.

v3:
* Fix ctl_adrr typo in Sparc-specific part of ns87415.c.
  (Noticed by Andrew Morton)

Subject: ide: use blk_rq_init() to initialize the request

This converts ide to use blk_rq_init to initialize the request.

This is a preparation for large command support, which needs to
initialize the request in a proper way (that is, just doing a memset()
will not work).
