+ * 2.02  Dec 11, 1994 -- Cache the TOC in the driver.
+ *                       Don't use SCMD_PLAYAUDIO_TI; it's not included

+ *                        blocks (like Pioneer drives).  Thanks to
+ *                        Richard Hirst <srh@gpt.co.uk> for diagnosing this.
+ *                       Properly supply the page number field in the
+ *                        MODE_SELECT command.
+ *                       PLAYAUDIO12 is broken on the Aztech; work around it.

+ *                        Minor other changes

+ *                     -- Fixed a memory leak where info->changer_info was
+ *                         malloc'ed but never free'd when closing the device.

+ * 4.11  Mar 12, 1998  -- Added support for the CDROM_SELECT_SPEED ioctl

+ *                         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

+ *
+ * 4.15  Aug 25, 1998  -- Updated ide-cd.h to respect mechine endianess,

+ *
+ * 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.

+/*
+ * 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
