4247656160 The long awaited stability patch set for the aic7xxx driver:
aic7770.c:
Simplify the initialization of adapters by pulling all card specific
initialization to the card specific modules.

eisaconf.c:
outb 0x80 instead of 0xc80.  The top byte is truncated anyway, and 0x80
was what was intended.

88f703b1f5 The long awaited stability patch set for the aic7xxx driver:
1) Use cpp to preprocess the sequencer code.

2) Convert all "magic numbers" to #defines shared by the sequencer and
   kernel driver via the aic7xxx_reg.h file.  (The assembler still needs
   to be re-written in lex/yacc to allow ~|& type constructions).

3) Raise ATN on parity errors for "in" phases and send an initiator detected
   error or message-in parity error message as appropriate.

4) Turn off the reselection hardware from the time or a (re)connection to
   busfree.  It seems that some fast targets were able to reconnect before
   the sequencer was able to see busfree.

5) The message buffer is considered "in-use" when there is a positive length
   count.  The ACTIVE_MSG flag was unnecesary.

6) Properly set SCB_NEXT_WAITING to SCB_LIST_HEAD in scbs being added to
   the waiting scb list.  This is a change in how the list code works to
   facilitate some planned work in the reset code.

7) The fields in the SCB have be re-arranged to be quad-word aligned.

8) The inb code has been rewritten to catch phasemisses and be more efficient.

9) Go back to "snooping the bus" to determine if the incomming identify
   message will be followed by a simple queue message.  Its much faster than
   doing a search through the SCBs.

10) Implement better tag range checking for incomming tags.

11) Make sdtr_to_rate more accurate (use 25 instead of 24 in calculations -
    must have been asleep that night).

12) Rearrange some routines to reduce code complexity and size.

13) Update comments and formatting.

14) Fixed bugs I've forgotten about??

2aec697e08 Fixed bugs introduced in rev. 1.127 (some broken 16650 support was
unintentionally committed):
- the fifo was completely disabled for low speeds.  Apart from being
  unnecessarily inefficient, this invalidated com->tx_fifo_size.
- `ftl' became a bogus name.
- the 16650 probe breaks the COM_NOFIFO() case and has other bugs
  (disabled, not fixed).

Fixed bogus change of the fifo settings for the non-speed of 0.  This
bug made the above fifo bug occur even at non-low speeds.

Fixed the modes of the cua devices.  It isn't possible to set the uid
and gid correctly since the kernel can't know who uucp.dialer is.

Register the devswitch at device attach time.  SYSINIT() is not
the right way to initialize devswitches (if anything :->).
Eventually, the devswitch should be deregistered at device detach
and/or unload time and reregistered at device attach time ...  Then
some com->gone tests could be removed.

Cleaned up some other recent changes.

956b9c95d2 Removed my devsw access functions [un]register_cdev() and
getmajorbyname() which were a better (sigh) temporary interface to
the going-away devswitches.

Note that SYSINIT()s to initialize the devswitches would be fatal
in syscons.c and pcvt_drv.c (and are bogus elsewhere) because they
get called independently of whether the device is attached; thus
devices that share a major clobber each other's devswitch entries
until the last one wins.

if somehow gets called).

1900eea896 Pass 3 of the great devsw changes
most devsw referenced functions are now static, as they are
in the same file as their devsw structure. I've also added DEVFS
support for nearly every device in the system, however
many of the devices have 'incorrect' names under DEVFS
because I couldn't quickly work out the correct naming conventions.
(but devfs won't be coming on line for a month or so anyhow so that doesn't
matter)

If you "OWN" a device which would normally have an entry in /dev
then search for the devfs_add_devsw() entries and munge to make them right..
check out similar devices to see what I might have done in them in you
can't see what's going on..
for a laugh compare conf.c conf.h defore and after... :)
I have not doen DEVFS entries for any DISKSLICE devices yet as that will be
a much more complicated job.. (pass 5 :)

pass 4 will be to make the devsw tables of type (cdevsw * )
rather than (cdevsw)
seems to work here..
complaints to the usual places.. :)
