Linux-2.6.12-rc2
Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!

+
+ 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.

+ 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.

+
+ * fdomain.c: New version from Rik Faith - version 5.22. Add support
+ for ISA-200S SCSI adapter.
+
+ * hosts.c: Spelling.
+
+ * qlogic.c: Update to version 0.38a. Add more support for PCMCIA.
+
+ * scsi.c: Mask device type with 0x1f during scan_scsis.
+ Add support for deadlocking, err, make that getting out of
+ deadlock situations that are created when we allow the user
+ to limit requests to one host adapter at a time.
+
+ * scsi.c: Bugfix - pass pid, not SCpnt as second arg to
+ scsi_times_out.
+
+ * scsi.c: Restore interrupt state to previous value instead of using
+ cli/sti pairs.
+

+ 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

+ changes appear from some unknown corner of the universe.
+
+ * Throughout: Change COMMAND_SIZE() to use SCpnt->cmd_len.

+ 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.

+ list.
+
+ scsi.c: (scan_scsis): Use linked list instead of knowledge about

+
+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.

+ * 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.

+ 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

+
+ * seagate.c: Add new compile time options for ARBITRATE,
+ SLOW_HANDSHAKE, and SLOW_RATE. Update assembly loops for transferring

+
+ * sd.c: Fix race condition for multiple disks. Use INIT_SCSI_REQUEST
+ instead of INIT_REQUEST. Allow sector sizes of 1024 and 256. For

+ * seagate.c: Use volatile keyword for memory-mapped register pointers.
+
+ * sr.c: Fix race condition, a la sd.c. Increase the number of retries
