Linux-2.6.12-rc2v2.6.12-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

+; be done in the NCR driver by precomputing them on the

+; 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.

+;
+; PURPOSE : process messages from a target.  msg_in is called when the 
+;       caller hasn't read the first byte of the message.  munge_message
+;       is called when the caller has read the first byte of the message,
+;       and left it in SFBR.  msg_in_restart is called when the caller 
+;       hasn't read the first byte of the message, and wishes RETURN
+;       to transfer control back to the address of the conditional
+;       CALL instruction rather than to the instruction after it.
+;
+;       Various int_* interrupts are generated when the host system
+;       needs to intervene, as is the case with SDTR, WDTR, and
+;       INITIATE RECOVERY messages.
+;
+;       When the host system handles one of these interrupts,
+;       it can respond by reentering at reject_message, 
+;       which rejects the message and returns control to
+;       the caller of msg_in or munge_msg, accept_message
+;       which clears ACK and returns control, or reply_message
+;       which sends the message pointed to by the DSA 
+;       msgout_other table indirect field.
+;
+;       DISCONNECT messages are handled by moving the command
+;       to the reconnect_dsa_queue.
+
+; NOTE: DSA should be valid when we get here - we cannot save both it
+;       and TEMP in this routine.
+
+;
+; INPUTS : DSA - SCSI COMMAND, SFBR - first byte of message (munge_msg
+;       only)
+;

+;

+;
+; PURPOSE : This is essentially the idle routine, where control lands
+;       when there are no new processes to schedule.  wait_reselect
+;       waits for reselection, selection, and new commands.
+;
+;       When a successful reselection occurs, with the aid 
+;       of fixed up code in each DSA, wait_reselect walks the 
+;       reconnect_dsa_queue, asking each dsa if the target ID
+;       and LUN match its.
+;
+;       If a match is found, a call is made back to reselected_ok,
+;       which through the miracles of self modifying code, extracts
+;       the found DSA from the reconnect_dsa_queue and then 
+;       returns control to the DSAs thread of execution.
+;
+; INPUTS : NONE
+;
+; CALLS : OK
+;
+; MODIFIES : DSA,
+;
+; EXITS : On successful reselection, control is returned to the 
+;       DSA which called reselected_ok.  If the WAIT RESELECT
+;       was interrupted by a new commands arrival signaled by 
+;       SIG_P, control is passed to schedule.  If the NCR is 
+;       selected, the host system is interrupted with an 
+;       int_err_selected which is usually responded to by
+;       setting DSP to the target_abort address.
