As a preparation for new device code, separated the various
functions the request->dev field had into the device proper,
request->rq_dev and a status field request->rq_status.
The 2nd argument of bios_param is now a kdev_t.
Wed Jul 19 10:43:15 1995 Michael Neuffer <neuffer@goofy.zdv.uni-mainz.de>
* scsi.c (scsi_proc_info): /proc/scsi/scsi now also lists all
attached devices.
* scsi_proc.c (proc_print_scsidevice): Added. Used by scsi.c and
eata_dma_proc.c to produce some device info for /proc/scsi.
* eata_dma.c (eata_queue)(eata_int_handler)(eata_scsi_done):
Changed handling of internal SCSI commands send to the HBA.
Wed Jul 19 10:09:17 1995 Michael Neuffer <neuffer@goofy.zdv.uni-mainz.de>
* Linux 1.3.11 released.
* eata_dma.c (eata_queue)(eata_int_handler): Added code to do
command latency measurements if requested by root through
/proc/scsi interface.
Throughout Use HZ constant for time references.
* eata_pio.c: Use HZ constant for time references.
* aic7xxx.c, aic7xxx.h, aic7xxx_asm.c: Changed copyright from BSD
to GNU style.
* scsi.h: Added READ_12 command opcode constant
Wed Jul 19 09:25:30 1995 Michael Neuffer <neuffer@goofy.zdv.uni-mainz.de>
* Linux 1.3.10 released.
* scsi_proc.c (dispatch_scsi_info): Removed unused variable.
Wed Jul 19 09:25:30 1995 Michael Neuffer <neuffer@goofy.zdv.uni-mainz.de>
* Linux 1.3.9 released.
* scsi.c Blacklist concept expanded to 'support' more device
deficiencies. blacklist[] renamed to device_list[]
(scan_scsis): Code cleanup.
* scsi_debug.c (scsi_debug_proc_info): Added support to control
device lockup simulation via /proc/scsi interface.
Wed Jul 19 09:22:34 1995 Michael Neuffer <neuffer@goofy.zdv.uni-mainz.de>
* Linux 1.3.7 released.
* scsi_proc.c: Fixed a number of bugs in directory handling
Wed Jul 19 09:18:28 1995 Michael Neuffer <neuffer@goofy.zdv.uni-mainz.de>
* Linux 1.3.5 released.
* Native wide, multichannel and /proc/scsi support now in official
kernel distribution.
* scsi.c/h, hosts.c/h et al reindented to increase readability
(especially on 80 column wide terminals).
* scsi.c, scsi_proc.c, ../../fs/proc/inode.c: Added
/proc/scsi/scsi which allows root to scan for hotplugged devices.
* scsi.c (scsi_proc_info): Added, to support /proc/scsi/scsi.
(scan_scsis): Added some 'spaghetti' code to allow scanning for
single devices.
Thu Jun 20 15:20:27 1995 Michael Neuffer <neuffer@goofy.zdv.uni-mainz.de>
* proc.c: Renamed to scsi_proc.c
Mon Jun 12 20:32:45 1995 Michael Neuffer <neuffer@goofy.zdv.uni-mainz.de>
* Linux 1.3.0 released.
Mon May 15 19:33:14 1995 Michael Neuffer <neuffer@goofy.zdv.uni-mainz.de>
* scsi.c: Added native multichannel and wide scsi support.
* proc.c (dispatch_scsi_info) (build_proc_dir_hba_entries):
Updated /proc/scsi interface.
Thu May 4 17:58:48 1995 Michael Neuffer <neuffer@goofy.zdv.uni-mainz.de>
* sd.c (requeue_sd_request): Zero out the scatterlist only if
scsi_malloc returned memory for it.
* eata_dma.c (register_HBA) (eata_queue): Add support for
large scatter/gather tables and set use_clustering accordingly
* hosts.c: Make use_clustering changeable in the Scsi_Host structure.
Wed Apr 12 15:25:52 1995 Eric Youngdale (eric@andante)
* Linux 1.2.5 released.
* buslogic.c: Update to version 1.15 (From Leonard N. Zubkoff).
Fixed interrupt routine to avoid races when handling multiple
complete commands per interrupt. Seems to come up with faster
cards.
* eata_dma.c: Update to 2.3.5r. Modularize. Improved error handling
throughout and fixed bug interrupt routine which resulted in shifted
status bytes. Added blink LED state checks for ISA and EISA HBAs.
Memory management bug seems to have disappeared ==> increasing
C_P_L_CURRENT_MAX to 16 for now. Decreasing C_P_L_DIV to 3 for
performance reasons.
* scsi.c: If we get a FMK, EOM, or ILI when attempting to scan
the bus, assume that it was just noise on the bus, and ignore
the device.
* scsi.h: Update and add a bunch of missing commands which we
were never using.
* sd.c: Use restore_flags in do_sd_request - this may result in
latency conditions, but it gets rid of races and crashes.
Do not save flags again when searching for a second command to
queue.
* st.c: Use bytes, not STP->buffer->buffer_size when reading
from tape.
Tue Apr 4 09:42:08 1995 Eric Youngdale (eric@andante)
* Linux 1.2.4 released.
* st.c: Fix typo - restoring wrong flags.
Wed Mar 29 06:55:12 1995 Eric Youngdale (eric@andante)
* Linux 1.2.3 released.
* st.c: Perform some waiting operations with interrupts off.
Is this correct???
Wed Mar 22 10:34:26 1995 Eric Youngdale (eric@andante)
* Linux 1.2.2 released.
* aha152x.c: Modularize. Add support for PCMCIA.
* eata.c: Update to version 2.0. Fixed bug preventing media
detection. If scsi_register_host returns NULL, fail gracefully.
* scsi.c: Detect as NEC (for photo-cd purposes) for the 84
and 25 models as "NEC_OLDCDR".
* scsi.h: Add define for NEC_OLDCDR
* sr.c: Add handling for NEC_OLDCDR. Treat as unknown.
* u14-34f.c: Update to version 2.0. Fixed same bug as in
eata.c.
Mon Mar 6 11:11:20 1995 Eric Youngdale (eric@andante)
* Linux 1.2.0 released. Yeah!!!

Big changes here.

(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.
Print hosts after we have identified all of them. Use info()
function if present, otherwise use name field.
* hosts.h: Change attach function to return int, not void.
Define number of device slots to allow for loadable devices.
Define tags to tell scsi module code what type of module we
are loading.

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.

address lines for the bios chips, but I am not entirely sure.
* buslogic.c: Set forbidden_addr stuff if using a buggy board.
* aha1740.c: Test for NULL pointer in SCtmp. This should not
occur, but a nice message is better than a kernel segfault.
