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!

+;
+; IMPORTANT : This code is self modifying due to the limitations of
+; the NCR53c7,8xx series chips. Persons debugging this code with
+; the remote debugger should take this into account, and NOT set
+; breakpoints in modified instructions.
+;
+; Design:
+; The NCR53c7,8xx family of SCSI chips are busmasters with an onboard
+; microcontroller using a simple instruction set.
+;
+; So, to minimize the effects of interrupt latency, and to maximize
+; throughput, this driver offloads the practical maximum amount
+; of processing to the SCSI chip while still maintaining a common
+; structure.
+;
+; Where tradeoffs were needed between efficiency on the older
+; chips and the newer NCR53c800 series, the NCR53c800 series
+; was chosen.
+;
+; While the NCR53c700 and NCR53c700-66 lacked the facilities to fully
+; automate SCSI transfers without host processor intervention, this
+; isn't the case with the NCR53c710 and newer chips which allow
+;
+; - reads and writes to the internal registers from within the SCSI
+; scripts, allowing the SCSI SCRIPTS(tm) code to save processor
+; state so that multiple threads of execution are possible, and also
+; provide an ALU for loop control, etc.
+;
+; - table indirect addressing for some instructions. This allows
+; pointers to be located relative to the DSA ((Data Structure
+; Address) register.
+;
+; These features make it possible to implement a mailbox style interface,
+; where the same piece of code is run to handle I/O for multiple threads
+; at once minimizing our need to relocate code. Since the NCR53c700/
+; NCR53c800 series have a unique combination of features, making a
+; a standard ingoing/outgoing mailbox system, costly, I've modified it.
+;
+; - Mailboxes are a mixture of code and data. This lets us greatly
+; simplify the NCR53c810 code and do things that would otherwise
+; not be possible.
+;
+; The saved data pointer is now implemented as follows :
+;
+; Control flow has been architected such that if control reaches
+; munge_save_data_pointer, on a restore pointers message or
+; reconnection, a jump to the address formerly in the TEMP register
+; will allow the SCSI command to resume execution.
+;
+
+;
+; Note : the DSA structures must be aligned on 32 bit boundaries,
+; since the source and destination of MOVE MEMORY instructions
+; must share the same alignment and this is the alignment of the
+; NCR registers.
+;
+
+; For some systems (MVME166, for example) dmode is always the same, so don't
+; waste time writing it

+; Once a device has initiated reselection, we need to compare it
+; against the singly linked list of commands which have disconnected
+; and are pending reselection. These commands are maintained in
+; an unordered singly linked list of DSA structures, through the
+; DSA pointers at their 'centers' headed by the reconnect_dsa_head
+; pointer.
+;
+; To avoid complications in removing commands from the list,
+; I minimize the amount of expensive (at eight operations per
+; addition @ 500-600ns each) pointer operations which must
+; be done in the NCR driver by precomputing them on the
+; host processor during dsa structure generation.
+;
+; The fixed-up per DSA code knows how to recognize the nexus
+; associated with the corresponding SCSI command, and modifies
+; the source and destination pointers for the MOVE MEMORY
+; instruction which is executed when reselected_ok is called
+; to remove the command from the list. Similarly, DSA is
+; loaded with the address of the next DSA structure and
+; reselected_check_next is called if a failure occurs.
+;
+; Perhaps more concisely, the net effect of the mess is
+;
+; for (dsa = reconnect_dsa_head, dest = &reconnect_dsa_head,
+; src = NULL; dsa; dest = &dsa->next, dsa = dsa->next) {
