Simplify the initialization of adapters by pulling all card specific
initialization to the card specific modules.
Set the Latency timer and Burst len to good values if thery are not
initialized during post or are reset during chip reset.
Properly identify and handle external SCB SRAM. The code was false
id'ing 255 SCBs on aic7880 chips.

Update comments and fix formating.
Pass struct ahc_data*'s to functions instead of unit numbers.
Take advantage of the quad word alignment of SCB fields.
Adapt to new sequencer changes:
1) Waiting scb list no longer has a tail.
2) Fill the message buffer as appropriate during a parity error.
3) Count all of the SGs involved in a residual instead of just
the current one.
The reset/abort code still needs a lot of work.

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

Initialise the "hidden" blueprint mount "mnt_op" and "mnt_vfc" fields so
that a statfs() on a devfs file would not panic anymore. Fixes PR#911.
Head-scratching by: Julian and Peter
sysctl handler (ouch!)
Add a "const" qualifier to the source of the copyin() and copyout()
functions - the other const warning in kern_sysctl.c was silenced when
copyout was declared as having a const source.. (which it is)
just like on SVR4.
This has no effect on any current programs in our source, but makes
the use of SVR4 code a little easier. There is no code or implementation
cost in the kernel.. This two-line change merely sets the modes on the ends
of the pipes to be bidirectional. There are no other changes.
and the ethernet address for non-root users.
I apologise to the world for propagating the ugliness of some of the code
constructs within ifconfig... Fixing them would just abou mean rewriting
most of the function call interfaces, something I didn't have the stomach
for. :-)
LKM loading if it was not configured into the system.
Note that the LKM for MFS is not enabled by default, but I got it working on
my machine.. I'll see what I did..
Install (optional) libutil.h with prototypes for the functions and
document this in the man page.
minor cleanups to the various routines, include the prototype file, declare
return codes etc.
and add selection traversal callbacks so context-sensitive behavior can
even be implemented for individual menu items. These work around the two
largest issues holding me back with some of my sysinstall changes.
