feb22b7f8e ide: add proper PCI PM support (v2)
* 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.

8185d5aa93 ide: /proc/ide/hd*/settings rework
* Add struct ide_devset, S_* flags, *DEVSET() & ide*_devset_*() macros.

* Add 'const struct ide_devset **settings' to ide_driver_t.

* Use 'const struct ide_devset **settings' in ide_drive_t instead of
  'struct ide_settings_s *settings'.  Then convert core code and device
  drivers to use struct ide_devset and co.:

  - device settings are no longer allocated dynamically for each device
    but instead there is an unique struct ide_devset instance per setting

  - device driver keeps the pointer to the table of pointers to its
    settings in ide_driver_t.settings

  - generic settings are kept in ide_generic_setting[]

  - ide_proc_[un]register_driver(), ide_find_setting_by_name(),
    ide_{read,write}_setting() and proc_ide_{read,write}_settings()
    are updated accordingly

  - ide*_add_settings() are removed

* Remove no longer used __ide_add_setting(), ide_add_setting(),
  __ide_remove_setting() and auto_remove_settings().

* Remove no longer used TYPE_*, SETTING_*, ide_procset_t
  and ide_settings_t.

* ->keep_settings, ->using_dma, ->unmask, ->noflush, ->dsc_overlap,
  ->nice1, ->addressing, ->wcache and ->nowerr ide_drive_t fields
  can now be bitfield flags.

While at it:

* Rename ide_find_setting_by_name() to ide_find_setting().

* Rename write_wcache() to set_wcache().

48fb2688aa ide: remove drive->driveid
* 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.

  - drivers/block/xsysace.c

eb3aff5530 ide: print message on error in ide_find_port_slot()
* Add DRV_NAME define to ide-h8300.c.

* Fix ide-h8300.c, swarm.c and sgiioc4.c to set .name field in
  struct ide_port_info to DRV_NAME, then convert these host drivers
  to use ide_find_port_slot() instead of ide_find_port().

* Print message on error in ide_find_port_slot().
