After rework settings will be no longer created dynamically

* Allow writes to ["io_32bit","unmaskirq"] settings also when
  drive->no_[io_32bit,unmask] is set (this is checked later inside
  set_[io_32bit,unmaskirq]() anywyay and keeps consistency with
  the corresponding HDIO_SET_[32BIT,UNMASKINTR] ioctls).

* Use max possible multi sectors value (16) as an allowed max for
  "multcount" setting.  set_multcount() set function checks against
  device's max possbile value anyway and it makes the proc setting
  consistent with the corresponding HDIO_SET_MULTCOUNT ioctl.

Bartlomiej Zolnierkiewicz 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.

  This leaves us with 3 users of struct hd_driveid in tree:

  - drivers/block/xsysace.c

Make drive->id an unnamed union so id can be accessed either by using

* Filter out "default" transfer mode values (0x00 - default PIO mode,
  0x01 - default PIO mode w/ IORDY disabled) in write handler for obsoleted
  /proc/ide/hd?/settings:current_speed setting.

  Allowing "default" transfer mode values is a dangerous thing to do as
  we don't support programming controller to the "default" transfer mode
  and devices often use different values for the default and maximum PIO
  mode (i.e. PIO2 default and PIO4 maximum) so the controller will stay
  programmed for higher PIO mode while device will use the lower PIO mode.

  There is no functionality loss as by using special IOCTLs device can
  still be programmed to "default" transfer modes (it is only useful for
  debugging/testing purposes anyway).

* Remove no longer needed IDE_HFLAG_ABUSE_SET_DMA_MODE host flag, it was
  previously used by few host drivers to program the controller to PIO0
  timings for "default" transfer mode == 0x01 (although some host drivers
  would program invalid PIO timings instead).

we can remove the action argument in ide_do_drive_cmd and ide_action_t
typedef.

This patch also includes two minor cleanups: 1) ide_do_drive_cmd
always succeeds so we don't need the return value; 2) the callers use
blk_rq_init before ide_do_drive_cmd so there is no need to initialize
rq->errors.

Bartlomiej Zolnierkiewicz 93de00fd1c ide: remove broken/dangerous HDIO_[UNREGISTER,SCAN]_HWIF ioctls (take 3)
hdparm explicitely marks HDIO_[UNREGISTER,SCAN]_HWIF ioctls as DANGEROUS
and given the number of bugs we can assume that there are no real users:

* DMA has no chance of working because DMA resources are released by
  ide_unregister() and they are never allocated again.

* Since ide_init_hwif_ports() is used for ->io_ports[] setup the ioctls
  don't work for almost all hosts with "non-standard" (== non ISA-like)
  layout of IDE taskfile registers (there is a lot of such host drivers).

* ide_port_init_devices() is not called when probing IDE devices so:
  - drive->autotune is never set and IDE host/devices are not programmed
    for the correct PIO/DMA transfer modes (=> possible data corruption)
  - host specific I/O 32-bit and IRQ unmasking settings are not applied
    (=> possible data corruption)
  - host specific ->port_init_devs method is not called (=> no luck with
    ht6560b, qd65xx and opti621 host drivers)

* ->rw_disk method is not preserved (=> no HPT3xxN chipsets support).

* ->serialized flag is not preserved (=> possible data corruption when
   using icside, aec62xx (ATP850UF chipset), cmd640, cs5530, hpt366
   (HPT3xxN chipsets), rz1000, sc1200, dtc2278 and ht6560b host drivers).

* ->ack_intr method is not preserved (=> needed by ide-cris, buddha,
  gayle and macide host drivers).

* ->sata_scr[] and sata_misc[] is cleared by ide_unregister() and it
  isn't initialized again (SiI3112 support needs them).

* To issue an ioctl() there need to be at least one IDE device present
  in the system.

* ->cable_detect method is not preserved + it is not called when probing
  IDE devices so cable detection is broken (however since DMA support is
  also broken it doesn't really matter ;-).

* Some objects which may have already been freed in ide_unregister()
  are restored by ide_hwif_restore() (i.e. ->hwgroup).

* ide_register_hw() may unregister unrelated IDE ports if free ide_hwifs[]
  slot cannot be found.

* When IDE host drivers are modular unregistered port may be re-used by
  different host driver that owned it first causing subtle bugs.

Since we now have a proper warm-plug support remove these ioctls,
then remove no longer needed:
- ide_register_hw() and ide_hwif_restore() functions
- 'init_default' and 'restore' arguments of ide_unregister()
- zeroeing of hwif->{dma,extra}_* fields in ide_unregister()

As an added bonus IDE core code size shrinks by ~3kB (x86-32).

v2:
* fix ide_unregister() arguments in cleanup_module() (Andrew Morton).

Bartlomiej Zolnierkiewicz 5b0c4b30a6 ide: remove IDE devices from /proc/ide/ before unregistering them
IDE devices need to be removed from /proc/ide/ _before_ being unregistered:

* Drop 'ide_hwif_t *hwif' argument from destroy_proc_ide_device()
  and use drive->hwif instead.

* Rename destroy_proc_ide_device() to ide_proc_unregister_device().

* Call ide_proc_unregister_device() in drive_release_dev().

* Remove no longer needed destroy_proc_ide_drives().

Andi Kleen 1f07e98829 Prevent IDE boot ops on NUMA system
Without this patch a Opteron test system here oopses at boot with
current git.

Calling to_pci_dev() on a NULL pointer gives a negative value so the
following NULL pointer check never triggers and then an illegal address
is referenced.  Check the unadjusted original device pointer for NULL
instead.

Bartlomiej Zolnierkiewicz 395d8ef5be ide-disk: fix flush requests (take 2)
commit 813a0eb233
Author: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com>
Date:   Fri Jan 25 22:17:10 2008 +0100

    ide: switch idedisk_prepare_flush() to use REQ_TYPE_ATA_TASKFILE requests

...

broke flush requests.

Allocating IDE command structure on the stack for flush requests is not
a very brilliant idea:

- idedisk_prepare_flush() only prepares the request and it doesn't wait
  for it to be completed

- there are can be multiple flush requests queued in the queue

Fix the problem (per hints from James Bottomley) by:
- dynamically allocating ide_task_t instance using kmalloc(..., GFP_ATOMIC)
- adding new taskfile flag (IDE_TFLAG_DYN)
- calling kfree() in ide_end_drive_command() if IDE_TFLAG_DYN is set
  (while at it rename 'args' to 'task' and fix whitespace damage)

[ This will be fixed properly before 2.6.25 but this bug is rather
  critical and the proper solution requires some more work + testing. ]

Thanks to Sebastian Siewior and Christoph Hellwig for reporting the
problem and testing patches (extra thanks to Sebastian for bisecting
it to the guilty commmit).
