		Big changes here.
	
		* eata_dma.*: New files from Michael Neuffer.
		(neuffer@goofy.zdv.uni-mainz.de).  Should support
		all eata/dpt cards.
	
		* hosts.c, Makefile: Add eata_dma.
	
		* README.st: Document MTEOM.
	
		Patches from me (ERY) to finish support for low-level loadable scsi.
		It now works, and is actually useful.
	
		* Throughout - add new argument to scsi_init_malloc that takes an
		additional parameter.  This is used as a priority to kmalloc,
		and you can specify the GFP_DMA flag if you need DMA-able memory.
	
		* Makefile: For source files that are loadable, always add name
		to SCSI_SRCS.  Fill in modules: target.
	
		* hosts.c:  Change next_host to next_scsi_host, and make global.

		Do not use waiting loops - use up and down mechanism as long
		as current != task[0].
	
		* scsi.c(scan_scsis): Do not use stack variables for I/O - this
		could be > 16Mb if we are loading a module at runtime (i.e. use
		scsi_init_malloc to get some memory we know will be safe).
	
		* scsi.c: Change dma freelist to be a set of pages.  This allows
		us to dynamically adjust the size of the list by adding more pages
		to the pagelist.  Fix scsi_malloc and scsi_free accordingly.
	
		* scsi_module.c: Fix include.
	
		* sd.c: Declare detach function.  Increment/decrement module usage
		count as required.  Fix init functions to allow loaded devices.
		Revalidate all new disks so we get the partition tables.  Define
		detach function.
	
		* sr.c: Likewise.
	
		* sg.c: Declare detach function.  Allow attachment of devices on
		loaded drivers.
	
		* st.c: Declare detach function.  Increment/decrement module usage
		count as required.

		changes appear from some unknown corner of the universe.
	
		* Throughout: Change COMMAND_SIZE() to use SCpnt->cmd_len.
	
		* Throughout: Change info() low level function to take a Scsi_Host
		pointer.  This way the info function can return specific
		information about the host in question, if desired.

		all I/O to certain other cards.  Helps prevent problems with some
		ISA motherboards.
	
		* hosts.h: Add usage_count to Scsi_Host_Template.

		Move abort timeout message.  Fix panic in request_queueable to
		print correct function name.
	
		* scsi.c: When incrementing usage count, walk block linked list
		for host, and or in SCSI_HOST_BLOCK bit.  When decrementing usage
		count to 0, clear this bit to allow usage to continue, wake up
		processes waiting.
	
	
		* scsi_ioctl.c: If we have an info() function, call it, otherwise
		if we have a "name" field, use it, else do nothing.

		generate.
	
		* sd.h: Add "has_part_table" bit to rscsi_disks.

		override command length in COMMAND_SIZE).
	
		* sr.c: Bugfix from Gerd in photocd code.
	
		* sr.c: Bugfix in get_sectorsize - always use scsi_malloc buffer -
		we cannot guarantee that the stack is < 16Mb.

	Sat Jul  9 15:01:03 1994  Eric Youngdale  (eric@esp22)
	
		More changes to eventually support loadable modules.  Mainly
		we want to use linked lists instead of arrays because it is easier
		to dynamically add and remove things this way.
	
		Quite a bit more work is needed before loadable modules are
		possible (and usable) with scsi, but this is most of the grunge
		work.
	
		* Linux 1.1.28 released.
	
		* scsi.c, scsi.h (allocate_device, request_queueable): Change
		argument from index into scsi_devices to a pointer to the
		Scsi_Device struct.
	
		* Throughout: Change all calls to allocate_device,
		request_queueable to use new calling sequence.
	
		* Throughout: Use SCpnt->device instead of
		scsi_devices[SCpnt->index].  Ugh - the pointer was there all along
		- much cleaner this way.
	
		* scsi.c (scsi_init_malloc, scsi_free_malloc): New functions -
		allow us to pretend that we have a working malloc when we
		initialize.  Use this instead of passing memory_start, memory_end
		around all over the place.
	
		* scsi.h, st.c, sr.c, sd.c, sg.c: Change *_init1 functions to use
		scsi_init_malloc, remove all arguments, no return value.
	
		* scsi.h: Remove index field from Scsi_Device and Scsi_Cmnd
		structs.
	
		* scsi.c (scsi_dev_init): Set up for scsi_init_malloc.
		(scan_scsis): Get SDpnt from scsi_init_malloc, and refresh
		when we discover a device.  Free pointer before returning.
		Change scsi_devices into a linked list.
	
		* scsi.c (scan_scsis): Change to only scan one host.
		(scsi_dev_init): Loop over all detected hosts, and scan them.
	
		* hosts.c  (scsi_init_free): Change so that  number of extra bytes
		is stored in struct, and we do not have to pass it each time.
	
		* hosts.h: Change Scsi_Host_Template struct to include "next" and
		"release" functions.  Initialize to NULL in all low level
		adapters.
	
		* hosts.c: Rename scsi_hosts to builtin_scsi_hosts, create linked
		list scsi_hosts, linked together with the new "next" field.
	
	Wed Jul  6 05:45:02 1994  Eric Youngdale  (eric@esp22)
	
		* Linux 1.1.25 released.
	
		* aha152x.c: Changes from Juergen - cleanups and updates.
	
		* sd.c, sr.c: Use new check_media_change and revalidate
		file_operations fields.
	
		* st.c, st.h: Add changes from Kai Makisara, dated Jun 22.
	
		* hosts.h: Change SG_ALL back to 0xff.  Apparently soft error
		in /dev/brain resulted in having this bumped up.
		Change first parameter in bios_param function to be Disk * instead
		of index into rscsi_disks.
	
		* sd_ioctl.c: Pass pointer to rscsi_disks element instead of index
		to array.
	
		* sd.h: Add struct name "scsi_disk" to typedef for Scsi_Disk.
	
		* scsi.c: Remove redundant Maxtor XT8760S from blacklist.
		In scsi_reset, add printk when DEBUG defined.
	
		* All low level drivers: Modify definitions of bios_param in
		appropriate way.
	
	Thu Jun 16 10:31:59 1994  Eric Youngdale  (eric@esp22)
	
		* Linux 1.1.20 released.
	
		* scsi_ioctl.c: Only pass down the actual number of characters
		required to scsi_do_cmd, not the one rounded up to a even number
		of sectors.
	
		* ultrastor.c: Changes from Caleb Epstein for 24f cards.  Support
		larger SG lists.
	
		* ultrastor.c: Changes from me - use scsi_register to register
		host.  Add some consistency checking,
	
	Wed Jun  1 21:12:13 1994  Eric Youngdale  (eric@esp22)
	
		* Linux 1.1.19 released.
	
		* scsi.h: Add new return code for reset() function:
		SCSI_RESET_PUNT.
	
		* scsi.c: Make SCSI_RESET_PUNT the same as SCSI_RESET_WAKEUP for
		now.
	
		* aha1542.c: If the command responsible for the reset is not
		pending, return SCSI_RESET_PUNT.
	
		* aha1740.c, buslogic.c, wd7000.c, ultrastor.c: Return
		SCSI_RESET_PUNT instead of SCSI_RESET_SNOOZE.
	
	Tue May 31 19:36:01 1994  Eric Youngdale  (eric@esp22)
	
		* buslogic.c: Do not print out message about "must be Adaptec"
		if we have detected a buslogic card.  Print out a warning message
		if we are configuring for >16Mb, since the 445S at board level
		D or earlier does not work right.  The "D" level board can be made
		to work by flipping an undocumented switch, but this is too subtle.
	
	    Changes based upon patches in Yggdrasil distribution.
	
		* sg.c, sg.h: Return sense data to user.
	
		* aha1542.c, aha1740.c, buslogic.c: Do not panic if
		sense buffer is wrong size.
	
		* hosts.c: Test for ultrastor card before any of the others.
	
		* scsi.c: Allow boot-time option for max_scsi_luns=? so that
		buggy firmware has an easy work-around.
	
	Sun May 15 20:24:34 1994  Eric Youngdale  (eric@esp22)
	
		* Linux 1.1.15 released.
	
		Post-codefreeze thaw...
	
		* buslogic.[c,h]: New driver from David Gentzel.
	
		* hosts.h: Add use_clustering field to explicitly say whether
		clustering should be used for devices attached to this host
		adapter.  The buslogic board apparently supports large SG lists,
		but it is apparently faster if sd.c condenses this into a smaller
		list.
	
		* sd.c: Use this field instead of heuristic.
	
		* All host adapter include files: Add appropriate initializer for
		use_clustering field.
	
		* scsi.h: Add #defines for return codes for the abort and reset
		functions.  There are now a specific set of return codes to fully
		specify all of the possible things that the low-level adapter
		could do.
	
		* scsi.c: Act based upon return codes from abort/reset functions.
	
		* All host adapter abort/reset functions: Return new return code.
	
		* Add code in scsi.c to help debug timeouts.  Use #define
		DEBUG_TIMEOUT to enable this.
	
		* scsi.c: If the host->irq field is set, use
		disable_irq/enable_irq before calling queuecommand if we
		are not already in an interrupt.  Reduce races, and we
		can be sloppier about cli/sti in the interrupt routines now
		(reduce interrupt latency).
	
		* constants.c: Fix some things to eliminate warnings.  Add some
		sense descriptions that were omitted before.
	
		* aha1542.c: Watch for SCRD from host adapter - if we see it, set
		a flag.  Currently we only print out the number of pending
		commands that might need to be restarted.
	
		* aha1542.c (aha1542_abort): Look for lost interrupts, OGMB still
		full, and attempt to recover.  Otherwise give up.
	
		* aha1542.c (aha1542_reset): Try BUS DEVICE RESET, and then pass
		DID_RESET back up to the upper level code for all commands running
		on this target (even on different LUNs).
	
	Sat May  7 14:54:01 1994
	
		* Linux 1.1.12 released.
	
		* st.c, st.h: New version from Kai.  Supports boot time
		specification of number of buffers.
	
		* wd7000.[c,h]: Updated driver from John Boyd.  Now supports
		more than one wd7000 board in machine at one time, among other things.
	
	Wed Apr 20 22:20:35 1994
	
		* Linux 1.1.8 released.
	
		* sd.c: Add a few type casts where scsi_malloc is called.
	
	Wed Apr 13 12:53:29 1994
	
		* Linux 1.1.4 released.
	
		* scsi.c: Clean up a few printks (use %p to print pointers).
	
	Wed Apr 13 11:33:02 1994
	
		* Linux 1.1.3 released.
	
		* fdomain.c: Update to version 5.16 (Handle different FIFO sizes
		better).
	
	Fri Apr  8 08:57:19 1994
	
		* Linux 1.1.2 released.
	
		* Throughout: SCSI portion of cluster diffs added.
	
	Tue Apr  5 07:41:50 1994
	
		* Linux 1.1 development tree initiated.
	
		* The linux 1.0 development tree is now effectively frozen except
		for obvious bugfixes.

		know to restart the command.  Change prototype of aha1740_reset
		to take a command pointer.
	
		* constants.c: Clean up a few things.

		that are on a scatter-gather capable host adapter.
	
		* seagate.c: Fix so that some parameters can be set from the lilo
		prompt.  Supply jumpstart flag if we are resetting and need the
		command restarted.   Fix so that we return 1 if we detect a card
		so that multiple card detection works correctly.  Add yet another
		signature for FD cards (950).  Add another signature for ST0x.
	
		* sg.c, sg.h: New files from Lawrence Foard for generic scsi
		access.
	
		* sr.c:  Add type casts for (void*) so that we can do pointer
		arithmetic.  Works with GCC without this, but it is not strictly
		correct.  Same bugfix as was in sd.c.  Increase read-ahead a la
		disk driver.
	
		* sr_ioctl.c: Use scsi_malloc buffer instead of buffer from stack
		since we cannot guarantee that the stack is < 16Mb.
	
		ultrastor.c: Update to support 24f properly (JFC's driver).
	
		wd7000.c: Supply jumpstart flag for reset.  Do not round up

	    * Throughout:  Use check_region/snarf_region for all low-level
	    drivers.
	
	    * aha1542.c: Do hard reset instead of soft (some ethercard probes
	    screw us up).
	
	    * scsi.c: Add new flag ASKED_FOR_SENSE so that we can tell if we are
	    in a loop whereby the device returns null sense data.
	
	    * sd.c: Add code to spin up a drive if it is not already spinning.
	    Do this one at a time to make it easier on power supplies.

	    * constants.c, constants.h: New files with ascii descriptions of
	    various conditions.
	
	    * Makefile: Do not try to count the number of low-level drivers,
	    just generate the list of .o files.
	
	    * aha1542.c: Replace 16 with sizeof(SCpnt->sense_buffer).  Add tests
	    for addresses > 16Mb, panic if we find one.
	
	    * aha1740.c: Ditto with sizeof().
	
	    * fdomain.c: Update to version 3.18.  Add new signature, register IRQ
	    with irqaction.  Use ID 7 for new board.  Be more intelligent about
	    obtaining the h/s/c numbers for biosparam.
	
	    * hosts.c: Do not depend upon Makefile generated count of the number
	    of low-level host adapters.
	
	    * scsi.c: Use array for scsi_command_size instead of a function.  Add
	    Texel cdrom and Maxtor XT-4380S to blacklist.  Allow compile time
	    option for no-multi lun scan.  Add semaphore for possible problems
	    with handshaking, assume device is faulty until we know it not to be
	    the case.  Add DEBUG_INIT symbol to dump info as we scan for devices.
	    Zero sense buffer so we can tell if we need to request it.  When
	    examining sense information, request sense if buffer is all zero.
	    If RESET, request sense information to see what to do next.
	
	    * scsi_debug.c: Change some constants to use symbols like INT_MAX.
	
	    * scsi_ioctl.c (kernel_scsi_ioctl): New function -for making ioctl
	    calls from kernel space.
	
	    * sd.c: Increase timeout to 300.  Use functions in constants.h to
	    display info.  Use scsi_malloc buffer for READ_CAPACITY, since
	    we cannot guarantee that a stack based buffer is < 16Mb.
	
	    * sd_ioctl.c: Add BLKFLSBUF ioctl.
	
	    * seagate.c: Add new compile time options for ARBITRATE,
	    SLOW_HANDSHAKE, and SLOW_RATE.  Update assembly loops for transferring
	    data.  Use kernel_scsi_ioctl to request mode page with geometry.
	
	    * sr.c: Use functions in constants.c to display messages.
	
	    * st.c: Support for variable block size.
	
	    * ultrastor.c: Do not use cache for tape drives.  Set
	    unchecked_isa_dma flag, even though this may not be needed (gets set
	    later).

	    when requesting sense information so that this can properly be
	    restored if we retry the command.  Set aside dma buffers assuming each
	    block is 1 page, not 1Kb minix block.
	
	    * scsi_ioctl.c: Add a few type casts.  Other minor changes.
	
	    * sd.c:  Correctly  free all scsi_malloc'd memory if we run out of
	    dma_pool. Store blocksize information for each partition.
	
	    * seagate.c: Minor cleanups here and there.
	
	    * sr.c: Set up blocksize array for all discs.  Fix bug in freeing
	    buffers if we run out of dma pool.

	    get decremented past zero.
	
	    * sd.c: Add block_fsync function to dispatch table.
	
	    * sr.c: Increase timeout to 500 from 250.  Add entry for sync in
	    dispatch table (supply NULL).  If we do not have a sectorsize,
	    try to get it in the sd_open function.  Add new function just to
	    obtain sectorsize.
	
	    * sr.h: Add needs_sector_size semaphore.
	
	    * st.c: Add NULL for fsync in dispatch table.

	    * seagate.c: New version from Drew.  Includes new signatures for FD
	    cards.  Support for 0ws jumper. Correctly initialize
	    scsi_hosts[hostnum].this_id.  Improved handing of
	    disconnect/reconnect, and support command linking.  Use
	    transfersize and underflow fields.  Support scatter-gather.
	
	    * sr.c, sr_ioctl.c: Use long instead of int for last parameter in sr_ioctl.
	    Use buffer and buflength in do_ioctl.  Patches from Chris Newbold for
	    scsi-2 audio commands.

	        Do not truncate number of cylinders at 1024 for biosparam call.
	
	    * aha1740.c: Fix a few minor bugs for multiple devices.
	        Same as above for biosparam.
	
	    * scsi.c: Add lockable semaphore for removable devices that can have
	    media removal prevented.  Add another signature for flopticals.
	    (allocate_device): Fix race condition.  Allow more space in dma pool
	    for blocksizes of up to 4Kb.
	
	    * scsi.h: Define COMMAND_SIZE.  Define a SCSI specific version of
	    INIT_REQUEST that can run with interrupts off.
	
	    * scsi_ioctl.c: Make ioctl_probe function more idiot-proof.  If
	    a removable device says ILLEGAL REQUEST to a door-locking command,
	    clear lockable flag.  Add SCSI_IOCTL_GET_IDLUN ioctl.  Do not attempt
	    to lock door for devices that do not have lockable semaphore set.
	
	    * sd.c: Fix race condition for multiple disks.  Use INIT_SCSI_REQUEST
	    instead of INIT_REQUEST.  Allow sector sizes of 1024 and 256.  For
	    removable disks that are not ready, mark them as having a media change
	    (some drives do not report this later).
	
	    * seagate.c: Use volatile keyword for memory-mapped register pointers.
	
	    * sr.c: Fix race condition, a la sd.c.  Increase the number of retries
	    to 1.  Use INIT_SCSI_REQUEST.  Allow 512 byte sector sizes.  Do a
	    read_capacity when we init the device so we know the size and
	    sectorsize.
	
	    * st.c: If ioctl not found in st.c, try scsi_ioctl for others.
	
	    * ultrastor.c: Do not truncate number of cylinders at 1024 for
	    biosparam call.
	
	    * wd7000.c: Ditto.
	    Throughout: Use COMMAND_SIZE macro to determine length of scsi
	    command.
	
	
	
	Sat Mar 13 17:31:29 1993
	
	    * 0.99pl7 released.
	
	    Throughout: Improve punctuation in some messages, and use new
	    verify_area syntax.
	
	    * aha1542.c: Handle unexpected interrupts better.
	
	    * scsi.c: Ditto.  Handle reset conditions a bit better, asking for
	    sense information and retrying if required.
	
	    * scsi_ioctl.c: Allow for 12 byte scsi commands.
	
	    * ultrastor.c: Update to use scatter-gather.
	
	Sat Feb 20 17:57:15 1993
	
	    * 0.99pl6 released.
	
	    * fdomain.c: Update to version 3.5.  Handle spurious interrupts
	    better.
	
	    * sd.c: Use register_blkdev function.
	
	    * sr.c: Ditto.
	
	    * st.c: Use register_chrdev function.
	
	    * wd7000.c: Undo previous change.
	
	Sat Feb  6 11:20:43 1993
	
	    * 0.99pl5 released.
	
	    * scsi.c: Fix bug in testing for UNIT_ATTENTION.
	
	    * wd7000.c: Check at more addresses for bios.  Fix bug in biosparam
	    (heads & sectors turned around).
	
	Wed Jan 20 18:13:59 1993
	
	    * 0.99pl4 released.
	
	    * scsi.c: Ignore leading spaces when looking for blacklisted devices.
	
	    * seagate.c: Add a few new signatures for FD cards.  Another patch
	    with SCint to fix race condition.  Use recursion_depth to keep track
	    of how many times we have been recursively called, and do not start
	    another command unless we are on the outer level.  Fixes bug
	    with Syquest cartridge drives (used to crash kernel), because
	    they do not disconnect with large data transfers.
	
	Tue Jan 12 14:33:36 1993
	
	    * 0.99pl3 released.
	
	    * fdomain.c: Update to version 3.3 (a few new signatures).
	
	    * scsi.c: Add CDU-541, Denon DRD-25X to blacklist.
	    (allocate_request, request_queueable): Init request.waiting to NULL if
	    non-buffer type of request.
	
	    * seagate.c:  Allow controller to be overridden with CONTROLLER symbol.
	    Set SCint=NULL when we are done, to remove race condition.
	
	    * st.c: Changes from Kai.
	
	Wed Dec 30 20:03:47 1992
	
	    * 0.99pl2 released.
	
	    * scsi.c: Blacklist back in.  Remove Newbury drive as other bugfix
	    eliminates need for it here.
	
	    * sd.c: Return ENODEV instead of EACCES if no such device available.
	    (sd_init) Init blkdev_fops earlier so that sd_open is available sooner.
	
	    * sr.c: Same as above for sd.c.
	
	    * st.c: Return ENODEV instead of ENXIO if no device.  Init chrdev_fops
	    sooner, so that it is always there even if no tapes.
	
	    * seagate.c (controller_type): New variable to keep track of ST0x or
	    FD.  Modify signatures list to indicate controller type, and init
	    controller_type once we find a match.
	
	    * wd7000.c (wd7000_set_sync): Remove redundant function.
	
	Sun Dec 20 16:26:24 1992
	
	    * 0.99pl1 released.
	
	    * scsi_ioctl.c: Bugfix - check dev->index, not dev->id against
	    NR_SCSI_DEVICES.
	
	    * sr_ioctl.c: Verify that device exists before allowing an ioctl.
	
	    * st.c: Patches from Kai - change timeout values, improve end of tape
	    handling.
	
	Sun Dec 13 18:15:23 1992
	
	    * 0.99 kernel released.  Baseline for this ChangeLog.
