      ide: add proper PCI PM support (v2) · feb22b7f
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Keep pointer to ->init_chipset method also in
  struct ide_host and set it in ide_host_alloc_all().

* Add ide_pci_suspend() and ide_pci_resume() helpers
  (default ->suspend and ->resume implementations).

* ->init_chipset can no longer be marked __devinit.

* Add proper PCI PM support to IDE PCI host drivers
  (rz1000.c and tc86c001.c are skipped for now since
  they need to be converted from using ->init_hwif
  to use ->init_chipset instead).

v2:
* Cleanup CONFIG_PM #ifdef-s per akpm's suggestion.

      hpt366: add hpt3xx_disable_fast_irq() helper · 1785192b
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Factor out disabling of "fast interrupt" prediction from
  init_hwif_hpt366() to hpt3xx_disable_fast_irq() helper.

* Use hpt3xx_disable_fast_irq() in ->init_chipset instead of
  ->init_hwif method.

  This is a preparation for adding proper PCI PM support.

While at it:

* Cache chip type in chip_type variable in hpt3xx_disable_fast_irq().

There should be no functional changes caused by this patch.

      ide: remove drive->driveid · 48fb2688
      由 Bartlomiej Zolnierkiewicz 提交于 
      * Factor out HDIO_[OBSOLETE,GET]_IDENTITY ioctls handling
  to ide_get_identity_ioctl().

* Use temporary buffer in ide_get_identity_ioctl() instead
  of accessing drive->id directly.

* Add ide_id_to_hd_driveid() inline to convert raw id into
  struct hd_driveid format (needed on big-endian).

* Use ide_id_to_hd_driveid() in ide_get_identity_ioctl(),
  cleanup ide_fix_driveid() and switch ide to use use raw id.

* Remove no longer needed drive->driveid.

  This leaves us with 3 users of struct hd_driveid in tree:
  - arch/um/drivers/ubd_kern.c
  - drivers/block/xsysace.c
  - drivers/usb/storage/isd200.c

While at it:

* Use ata_id_u{32,64}() and ata_id_has_{dma,lba,iordy}() macros.

There should be no functional changes caused by this patch.

      ide: make drive->id an union (take 2) · 4dde4492
      由 Bartlomiej Zolnierkiewicz 提交于 
      Make drive->id an unnamed union so id can be accessed either by using
'u16 *id' or 'struct hd_driveid *driveid'.  Then convert all existing
drive->id users accordingly (using 'u16 *id' when possible).

This is an intermediate step to make ide 'struct hd_driveid'-free.

While at it:

- Add missing KERN_CONTs in it821x.c.

- Use ATA_ID_WORDS and ATA_ID_*_LEN defines.

- Remove unnecessary checks for drive->id.

- s/drive_table/table/ in ide_in_drive_list().

- Cleanup ide_config_drive_speed() a bit.

- s/drive1/dev1/ & s/drive0/dev0/ in ide_undecoded_slave().

v2:
Fix typo in drivers/ide/ppc/pmac.c. (From Stephen Rothwell)

There should be no functional changes caused by this patch.

      ide: Fix pointer arithmetic in hpt3xx driver code (3rd try) · 62ff2ecf
      由 Masoud Sharbiani 提交于 
      git commit 74811f35 causes crash at
module load (or boot) time on my machine with a hpt374 controller.
The reason for this is that for initializing second controller which sets
(hwif->dev == host->dev[1]) to true (1), adds 1 to a void ptr, which
advances it by one byte instead of advancing it by sizeof(hpt_info) bytes.
Because of this, all initialization functions get corrupted data in info
variable which causes a crash at boot time.

This patch fixes that and makes my machine boot again.

The card itself is a HPT374 raid conroller: Here is the lspci -v output:
