+ * (from mlord)       -- minor changes to cdrom_setup()
+ *                    -- renamed ide_dev_s to ide_drive_t, enable irq on 
command

+ *                       add audio ioctls.
+ * 2.01  Dec  3, 1994 -- Rework packet command interface to handle devices
+ *                       which send an interrupt when ready for a command.
+ * 2.02  Dec 11, 1994 -- Cache the TOC in the driver.
+ *                       Don't use SCMD_PLAYAUDIO_TI; it's not included
+ *                       in the current version of ATAPI.
+ *                       Try to use LBA instead of track or MSF addressing
+ *                       when possible.
+ *                       Don't wait for READY_STAT.
+ * 2.03  Jan 10, 1995 -- Rewrite block read routines to handle block sizes
+ *                       other than 2k and to move multiple sectors in a

+ *                       Always try to do a request_sense after
+ *                        a failed command.
+ *                       Include an option to give textual descriptions

+ *                        showed up if the drive returned data in 512 byte
+ *                        blocks (like Pioneer drives).  Thanks to
+ *                        Richard Hirst <[EMAIL PROTECTED]> for diagnosing 
this.
+ *                       Properly supply the page number field in the
+ *                        MODE_SELECT command.
+ *                       PLAYAUDIO12 is broken on the Aztech; work around it.
+ * 2.05x Aug 11, 1995 -- lots of data structure renaming/restructuring in ide.c

+ *                       Try to load the disk on open.
+ *                       Implement CDROMEJECT_SW ioctl (off by default).
+ *                       Read total cdrom capacity during open.
+ *                       Rearrange logic in cdrom_decode_status.  Issue

+ * 3.01  Sep  2, 1995 -- Fix ordering of reenabling interrupts in
+ *                        cdrom_queue_request.

+ *                          using the generic cdrom driver.
+ *                     -- Fully integrated with the 2.1.X kernel.

+ *                        Added identifier so new Sanyo CD-changer works
+ *                        Better detection if door locking isn't supported

+ *                     -- Fixed a memory leak where info->changer_info was

+ *                         <[EMAIL PROTECTED]>, a patch for 2.0.33
+ *                         by Toni Giorgino <[EMAIL PROTECTED]>, the SCSI
+ *                         version, and my own efforts.  -erik
+ *                     -- Fixed a stupid bug which egcs was kind enough to
+ *                         inform me of where "Illegal mode for this track"
+ *                         was never returned due to a comparison on data
+ *                         types of limited range.
+ * 4.12  Mar 29, 1998  -- Fixed bug in CDROM_SELECT_SPEED so write speed is
+ *                         now set ionly for CD-R and CD-RW drives.  I had
+ *                         removed this support because it produced errors.
+ *                         It produced errors _only_ for non-writers. duh.
+ * 4.13  May 05, 1998  -- Suppress useless "in progress of becoming ready"
+ *                         messages, since this is not an error.
+ *                     -- Change error messages to be const
+ *                     -- Remove a "\t" which looks ugly in the syslogs
+ * 4.14  July 17, 1998 -- Change to pointing to .ps version of ATAPI spec
+ *                         since the .pdf version doesn't seem to work...
+ *                     -- Updated the TODO list to something more current.
+ *
+ * 4.15  Aug 25, 1998  -- Updated ide-cd.h to respect mechine endianess,
+ *                         patch thanks to "Eddie C. Dost" <[EMAIL PROTECTED]>
+ *
+ * 4.50  Oct 19, 1998  -- New maintainers!
+ *                         Jens Axboe <[EMAIL PROTECTED]>
+ *                         Chris Zwilling <[EMAIL PROTECTED]>
+ *
+ * 4.51  Dec 23, 1998  -- Jens Axboe <[EMAIL PROTECTED]>
+ *                      - ide_cdrom_reset enabled since the ide subsystem
+ *                         handles resets fine now. <[EMAIL PROTECTED]>
+ *                      - Transfer size fix for Samsung CD-ROMs, thanks to
+ *                        "Ville Hallik" <[EMAIL PROTECTED]>.
+ *                      - other minor stuff.
+ *
+ * 4.52  Jan 19, 1999  -- Jens Axboe <[EMAIL PROTECTED]>
+ *                      - Detect DVD-ROM/RAM drives
+ *
+ * 4.53  Feb 22, 1999   - Include other model Samsung and one Goldstar
+ *                         drive in transfer size limit.
+ *                      - Fix the I/O error when doing eject without a medium
+ *                         loaded on some drives.
+ *                      - CDROMREADMODE2 is now implemented through
+ *                         CDROMREADRAW, since many drives don't support
+ *                         MODE2 (even though ATAPI 2.6 says they must).
+ *                      - Added ignore parameter to ide-cd (as a module), eg
+ *                             insmod ide-cd ignore='hda hdb'
+ *                         Useful when using ide-cd in conjunction with
+ *                         ide-scsi. TODO: non-modular way of doing the
+ *                         same.
+ *
+ * 4.54  Aug 5, 1999   - Support for MMC2 class commands through the generic
+ *                       packet interface to cdrom.c.
+ *                     - Unified audio ioctl support, most of it.
+ *                     - cleaned up various deprecated verify_area().
+ *                     - Added ide_cdrom_packet() as the interface for
+ *                       the Uniform generic_packet().
+ *                     - bunch of other stuff, will fill in logs later.
+ *                     - report 1 slot for non-changers, like the other
+ *                       cd-rom drivers. don't report select disc for
+ *                       non-changers as well.
+ *                     - mask out audio playing, if the device can't do it.
+ *
+ * 4.55  Sep 1, 1999   - Eliminated the rest of the audio ioctls, except
+ *                       for CDROMREADTOC[ENTRY|HEADER]. Some of the drivers
+ *                       use this independently of the actual audio handling.
+ *                       They will disappear later when I get the time to
+ *                       do it cleanly.
+ *                     - Minimize the TOC reading - only do it when we
+ *                       know a media change has occurred.
+ *                     - Moved all the CDROMREADx ioctls to the Uniform layer.

- *                         ide-scsi. TODO: non-modular way of doing the
- *                         same.
- *
- * 4.54  Aug 5, 1999   - Support for MMC2 class commands through the generic
- *                       packet interface to cdrom.c.
- *                     - Unified audio ioctl support, most of it.
- *                     - cleaned up various deprecated verify_area().
- *                     - Added ide_cdrom_packet() as the interface for
- *                       the Uniform generic_packet().
- *                     - bunch of other stuff, will fill in logs later.
- *                     - report 1 slot for non-changers, like the other
- *                       cd-rom drivers. don't report select disc for
- *                       non-changers as well.
- *                     - mask out audio playing, if the device can't do it.
- *
- * 4.55  Sep 1, 1999   - Eliminated the rest of the audio ioctls, except
- *                       for CDROMREADTOC[ENTRY|HEADER]. Some of the drivers
- *                       use this independently of the actual audio handling.
- *                       They will disappear later when I get the time to
- *                       do it cleanly.
- *                     - Minimize the TOC reading - only do it when we
- *                       know a media change has occurred.
- *                     - Moved all the CDROMREADx ioctls to the Uniform layer.

- *                       some fixes for CDI.
- *                     - CD-ROM leaving door locked fix from Andries
- *                       Brouwer <[EMAIL PROTECTED]>
- *                     - Erik Andersen <[EMAIL PROTECTED]> unified
- *                       commands across the various drivers and how
- *                       sense errors are handled.
- *

- *                     - Stop spewing errors to log when magicdev polls with
- *                       TEST_UNIT_READY on some drives.
- *                     - Various fixes from Tobias Ringstrom:
- *                       tray if it was locked prior to the reset.
- *                       - cdrom_read_capacity returns one frame too little.
