Hi,
More "uninteresting" IDE changes:
- make all host drivers use struct ide_port_info
- sanitize command/request completion API
- replace ide_task_t by struct ide_cmd
- improve debugging scheme (from Borislav Petkov)
- misc fixes/cleanups
Linus, please pull from:

These changes are not _that_ uninteresting to not apply them. ;)
More importantly they are holding back "part 3"...

* [git pull] IDE updates part 2

Hi,
More IDE changes for 2.6.31 merge window:
* Improved Host Protected Area handling [ http://lwn.net/Articles/335913/ ].
* Use PIO Mode 0 during probe if possible -- increases chance of successful
probe on BIOS/firmware-less systems (Joao Ramos, Hugh Dickins).
* Generalized nIEN quirks handling (some older disks don't handle IRQ
[un]masking well and we need a special treatment for them).
* pdc202xx_old host driver fixes (Sergei Shtylyov).
* ide-tape fixes (Borislav Petkov).
* Misc fixes/cleanups.

From: Bartlomiej Zolnierkiewicz @ 2009-01-02 16:59 UTC (permalink / raw)
To: Linus Torvalds; +Cc: Andrew Morton, Stephen Rothwell, linux-ide, linux-kernel
First IDE updates in 2009, this time:
* Fix IDE to not process commands in IRQ-context and than switch the
subsystem to use per-device request queue locks instead of (ab)using
hwgroup locks for this purpose. Besides being obvious IRQ-latency
and scalability improvement this decreases complexity of core code
greatly (~100 LOC of very tricky code gone) and makes maintainance
work much easier.
[ Thanks to Elias Oltmanns for his work on reviewing these changes
and catching some issues early. ]
* Scheduled removal of deprecated ide-scsi device driver.
We've been discouraging using ide-scsi since early 2.5.x days as the
driver contains unfixable problems with error handling and lifetimes
of IDE/SCSI objects. There is now consensus between IDE/SCSI people
that both (recently rewritten) native ide-{cd,gd,tape} drivers from
IDE side and proper ATA-SCSI emulation (libata) from SCSI side offer
a better alternative.
The driver has been officially orphaned for a year and then scheduled
for removal for the last 4 months so this shouldn't come as surprise
(I didn't got a single user complaint about this and ide-scsi has even
been broken by some unrelated kernel changes for few kernel releases
in the past without anybody noticing).
(from FUJITA Tomonori and Borislav Petkov)
* Fix multiple nested big stack usage in ide-floppy.c.
(from Linus himself, testing/merging handled by Borislav)
* Preparations to switch ide-cd device driver to use generic ATAPI code
which will happen in the next IDE updates pull request.
(from Borislav)
* Misc fixups/cleanups.
All above changes have been in linux-next for some time now...

- WARNING: ide-scsi is no longer needed for cd writing applications!

- This will provide SCSI host adapter emulation for IDE ATAPI devices,

- * Emulation of a SCSI host adapter for IDE ATAPI devices.
- *
- * With this driver, one can use the Linux SCSI drivers instead of the
- * native IDE ATAPI drivers.
- *
- * Ver 0.1 Dec 3 96 Initial version.
- * Ver 0.2 Jan 26 97 Fixed bug in cleanup_module() and added emulation
- * of MODE_SENSE_6/MODE_SELECT_6 for cdroms. Thanks
- * to Janos Farkas for pointing this out.
- * Avoid using bitfields in structures for m68k.
- * Added Scatter/Gather and DMA support.
- * Ver 0.4 Dec 7 97 Add support for ATAPI PD/CD drives.
- * Use variable timeout for each command.
- * Ver 0.5 Jan 2 98 Fix previous PD/CD support.
- * Allow disabling of SCSI-6 to SCSI-10 transformation.
- * Ver 0.6 Jan 27 98 Allow disabling of SCSI command translation layer
- * for access through /dev/sg.
- * Fix MODE_SENSE_6/MODE_SELECT_6/INQUIRY translation.
- * Ver 0.7 Dec 04 98 Ignore commands where lun != 0 to avoid multiple
- * detection of devices with CONFIG_SCSI_MULTI_LUN
- * Ver 0.8 Feb 05 99 Optical media need translation too. Reverse 0.7.
- * Ver 0.9 Jul 04 99 Fix a bug in SG_SET_TRANSFORM.
- * Ver 0.91 Jun 10 02 Fix "off by one" error in transforms
- * Ver 0.92 Dec 31 02 Implement new SCSI mid level API
