+ *                       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

+ *                        blocks (like Pioneer drives).  Thanks to

+ *                       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

+ *
+ * 4.02  Dec 01, 1996  -- Applied patch from Gadi Oxman <gadio@netvision.net.il>

+ *                        Better detection if door locking isn't supported
+ *
+ * 4.06  Dec 17, 1997  -- fixed endless "tray open" messages  -ml

+ *                         by Toni Giorgino <toni@pcape2.pi.infn.it>, 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" <ecd@skynet.be>
+ *
+ * 4.50  Oct 19, 1998  -- New maintainers!
+ *                         Jens Axboe <axboe@image.dk>
+ *                         Chris Zwilling <chris@cloudnet.com>
+ *
+ * 4.51  Dec 23, 1998  -- Jens Axboe <axboe@image.dk>
+ *                      - ide_cdrom_reset enabled since the ide subsystem
+ *                         handles resets fine now. <axboe@image.dk>
+ *                      - Transfer size fix for Samsung CD-ROMs, thanks to
+ *                        "Ville Hallik" <ville.hallik@mail.ee>.
+ *                      - other minor stuff.
+ *
+ * 4.52  Jan 19, 1999  -- Jens Axboe <axboe@image.dk>
+ *                      - 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.

+/*
+ * Many thanks to Lode Leroy <Lode.Leroy@www.ibase.be>, who tested so many
+ * ALPHA patches to this driver on an EASYSTOR LS-120 ATAPI floppy drive.
+ *
+ * Ver 0.1   Oct 17 96   Initial test version, mostly based on ide-tape.c.
+ * Ver 0.2   Oct 31 96   Minor changes.
+ * Ver 0.3   Dec  2 96   Fixed error recovery bug.
+ * Ver 0.4   Jan 26 97   Add support for the HDIO_GETGEO ioctl.
+ * Ver 0.5   Feb 21 97   Add partitions support.
+ *                       Use the minimum of the LBA and CHS capacities.
+ *                       Avoid hwgroup->rq == NULL on the last irq.
+ *                       Fix potential null dereferencing with DEBUG_LOG.
+ * Ver 0.8   Dec  7 97   Increase irq timeout from 10 to 50 seconds.
+ *                       Add media write-protect detection.
+ *                       Issue START command only if TEST UNIT READY fails.
+ *                       Add work-around for IOMEGA ZIP revision 21.D.
+ *                       Remove idefloppy_get_capabilities().
+ * Ver 0.9   Jul  4 99   Fix a bug which might have caused the number of
+ *                        bytes requested on each interrupt to be zero.
+ *                        Thanks to <shanos@es.co.nz> for pointing this out.
+ * Ver 0.9.sv Jan 6 01   Sam Varshavchik <mrsam@courier-mta.com>
+ *                       Implement low level formatting.  Reimplemented
+ *                       IDEFLOPPY_CAPABILITIES_PAGE, since we need the srfp
+ *                       bit.  My LS-120 drive barfs on
+ *                       IDEFLOPPY_CAPABILITIES_PAGE, but maybe it's just me.
+ *                       Compromise by not reporting a failure to get this
+ *                       mode page.  Implemented four IOCTLs in order to
+ *                       implement formatting.  IOCTls begin with 0x4600,
+ *                       0x46 is 'F' as in Format.
+ *            Jan 9 01   Userland option to select format verify.
+ *                       Added PC_SUPPRESS_ERROR flag - some idefloppy drives
+ *                       do not implement IDEFLOPPY_CAPABILITIES_PAGE, and
+ *                       return a sense error.  Suppress error reporting in
+ *                       this particular case in order to avoid spurious
+ *                       errors in syslog.  The culprit is
+ *                       idefloppy_get_capability_page(), so move it to
+ *                       idefloppy_begin_format() so that it's not used
+ *                       unless absolutely necessary.
+ *                       If drive does not support format progress indication
+ *                       monitor the dsc bit in the status register.
+ *                       Also, O_NDELAY on open will allow the device to be
+ *                       opened without a disk available.  This can be used to
+ *                       open an unformatted disk, or get the device capacity.
+ * Ver 0.91  Dec 11 99   Added IOMEGA Clik! drive support by
+ *                 <paul@paulbristow.net>
+ * Ver 0.92  Oct 22 00   Paul Bristow became official maintainer for this
+ *                         driver.  Included Powerbook internal zip kludge.
+ * Ver 0.93  Oct 24 00   Fixed bugs for Clik! drive
+ *                        no disk on insert and disk change now works
+ * Ver 0.94  Oct 27 00   Tidied up to remove strstr(Clik) everywhere
+ * Ver 0.95  Nov  7 00   Brought across to kernel 2.4
+ * Ver 0.96  Jan  7 01   Actually in line with release version of 2.4.0
+ *                       including set_bit patch from Rusty Russell
+ * Ver 0.97  Jul 22 01   Merge 0.91-0.96 onto 0.9.sv for ac series
+ * Ver 0.97.sv Aug 3 01  Backported from 2.4.7-ac3
+ * Ver 0.98  Oct 26 01   Split idefloppy_transfer_pc into two pieces to
+ *                        fix a lost interrupt problem. It appears the busy
+ *                        bit was being deasserted by my IOMEGA ATAPI ZIP 100
+ *                        drive before the drive was actually ready.
+ * Ver 0.98a Oct 29 01   Expose delay value so we can play.
+ * Ver 0.99  Feb 24 02   Remove duplicate code, modify clik! detection code
+ *                        to support new PocketZip drives

- *                         by Toni Giorgino <toni@pcape2.pi.infn.it>, the SCSI
- *                         version, and my own efforts.  -erik
- *                     -- Fixed a stupid bug which egcs was kind enough to

- *                         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

- *                         patch thanks to "Eddie C. Dost" <ecd@skynet.be>
- *
- * 4.50  Oct 19, 1998  -- New maintainers!
- *                         Jens Axboe <axboe@image.dk>
- *                         Chris Zwilling <chris@cloudnet.com>
- *
- * 4.51  Dec 23, 1998  -- Jens Axboe <axboe@image.dk>
- *                      - ide_cdrom_reset enabled since the ide subsystem
- *                         handles resets fine now. <axboe@image.dk>
- *                      - Transfer size fix for Samsung CD-ROMs, thanks to
- *                        "Ville Hallik" <ville.hallik@mail.ee>.
- *                      - other minor stuff.
- *
- * 4.52  Jan 19, 1999  -- Jens Axboe <axboe@image.dk>
- *                      - 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.
- *                      - Heiko Eißfeldt <heiko@colossus.escape.de> supplied
- *                        some fixes for CDI.
- *                      - CD-ROM leaving door locked fix from Andries
- *                        Brouwer <Andries.Brouwer@cwi.nl>
- *                      - Erik Andersen <andersen@xmission.com> unified
- *                        commands across the various drivers and how
- *                        sense errors are handled.
- *
- * 4.56  Sep 12, 1999   - Removed changer support - it is now in the
- *                        Uniform layer.
- *                      - Added partition based multisession handling.
- *                      - Mode sense and mode select moved to the
- *                        Uniform layer.
- *                      - Fixed a problem with WPI CDS-32X drive - it
- *                        failed the capabilities 
- *
- * 4.57  Apr 7, 2000    - Fixed sense reporting.
- *                      - Fixed possible oops in ide_cdrom_get_last_session()
- *                      - Fix locking mania and make ide_cdrom_reset relock
- *                      - 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.
- *                        - Fix real capacity reporting.
- *
- * 4.58  May 1, 2000    - Clean up ACER50 stuff.

- *
- * 4.59  Aug 11, 2000   - Fix changer problem in cdrom_read_toc, we weren't
- *                        correctly sensing a disc change.
- *                      - Rearranged some code
- *                      - Use extended sense on drives that support it for
- *                        correctly reporting tray status -- from

- * 4.60  Dec 17, 2003   - Add mt rainier support
- *                      - Bump timeout for packet commands, matches sr
- *                      - Odd stuff
- * 4.61  Jan 22, 2004   - support hardware sector sizes other than 2kB,

- * Many thanks to Lode Leroy <Lode.Leroy@www.ibase.be>, who tested so many

- *
- * Ver 0.1   Oct 17 96   Initial test version, mostly based on ide-tape.c.
- * Ver 0.2   Oct 31 96   Minor changes.
- * Ver 0.3   Dec  2 96   Fixed error recovery bug.
- * Ver 0.4   Jan 26 97   Add support for the HDIO_GETGEO ioctl.
- * Ver 0.5   Feb 21 97   Add partitions support.
- *                       Use the minimum of the LBA and CHS capacities.
- *                       Avoid hwgroup->rq == NULL on the last irq.
- *                       Fix potential null dereferencing with DEBUG_LOG.
- * Ver 0.8   Dec  7 97   Increase irq timeout from 10 to 50 seconds.
- *                       Add media write-protect detection.
- *                       Issue START command only if TEST UNIT READY fails.
- *                       Add work-around for IOMEGA ZIP revision 21.D.
- *                       Remove idefloppy_get_capabilities().
- * Ver 0.9   Jul  4 99   Fix a bug which might have caused the number of
- *                        bytes requested on each interrupt to be zero.
- *                        Thanks to <shanos@es.co.nz> for pointing this out.
- * Ver 0.9.sv Jan 6 01   Sam Varshavchik <mrsam@courier-mta.com>
- *                       Implement low level formatting.  Reimplemented
- *                       IDEFLOPPY_CAPABILITIES_PAGE, since we need the srfp
- *                       bit.  My LS-120 drive barfs on
- *                       IDEFLOPPY_CAPABILITIES_PAGE, but maybe it's just me.
- *                       Compromise by not reporting a failure to get this
- *                       mode page.  Implemented four IOCTLs in order to

- *                       0x46 is 'F' as in Format.
- *            Jan 9 01   Userland option to select format verify.
- *                       Added PC_SUPPRESS_ERROR flag - some idefloppy drives
- *                       do not implement IDEFLOPPY_CAPABILITIES_PAGE, and
- *                       return a sense error.  Suppress error reporting in
- *                       this particular case in order to avoid spurious

- *                       unless absolutely necessary.
- *                       If drive does not support format progress indication
- *                       monitor the dsc bit in the status register.
