are about to go in. This is to fix the problem with the ibcs2 and linux
lkm's not being able to call the sysv ipc functions unless the build is
modified.
in the future, these drivers won't need to maintain an array of
configured units. They still need to because ISA interrupt handlers
take a unit number. :(
Pass "softc" pointers instead of unit numbers to many functions that
did a conversion of unit->softc anyway.

whether of not to automatically #define EXCLUDE_AUDIO; MSS is a real
audio device and we should not #define EXCLUDE_AUDIO if we have one.
(And I want it because it's the only mixer-capable audio driver that I
can use with my crummy Packard Bell (nee Aztech) audio board.)
This fixes the very confusing condition where having all of this:
mss0 at 0x530 irq 10 drq 1 on isa
gus0: <MS Sound System (CS4231)>
opl0 at 0x388 on isa
opl0: <Yamaha OPL-3 FM>
mpu0 at 0x300 irq 9 drq 0 on isa
mpu0: <MPU-401 MIDI Interface 0.0 >
will still give you this:
% cat /dev/sndstat
SoundCard Error: The soundcard system has not been configured
Also remove an unnecessary newline in the printf() message for the
'gus0' device shown above so that we don't wind up printing a blank
line between mss0 and gus0.
was overlapping with another file, and making some undesirable behavior a
little worse - it's triggering a bug in config that appears to have been
there for some time (before the options files, anyway.)
to enable IP forwarding, use sysctl(8). Also did the same for IPX,
which involved inventing a completely new MIB from whole cloth (which
I may not quite have correct); be aware of this if you use IPX forwarding.
(The two should never have been controlled by the same option anyway.)
Simplify the initialization of adapters by pulling all card specific
initialization to the card specific modules.
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.

enough nodes for the number of ports on the last module, not the number
of ports _total_ that the driver is managing...
Submitted by: Robert Sanders <rsanders@mindspring.com>
Nobody in our regular source tree, or in the non-distfile part of the
ports tree does use /dev/io anyway, so this might be replaced by
another scenario some day.
looking at a high resolution clock for each of the following events:
function call, function return, interrupt entry, interrupt exit,
and interesting branches. The differences between the times of
these events are added at appropriate places in a ordinary histogram
(as if very fast statistical profiling sampled the pc at those
places) so that ordinary gprof can be used to analyze the times.
gmon.h:
Histogram counters need to be 4 bytes for microsecond resolutions.
They will need to be larger for the 586 clock.
The comments were vax-centric and wrong even on vaxes. Does anyone
disagree?
gprof4.c:
The standard gprof should support counters of all integral sizes
and the size of the counter should be in the gmon header. This
hack will do until then. (Use gprof4 -u to examine the results
of non-statistical profiling.)
config/*:
Non-statistical profiling is configured with `config -pp'.
`config -p' still gives ordinary profiling.
kgmon/*:
Non-statistical profiling is enabled with `kgmon -B'. `kgmon -b'
still enables ordinary profiling (and distables non-statistical
profiling) if non-statistical profiling is configured.
we can see if it's a small distance beyond the end, or way out. This may
give some clues as to whether it is being caused by something coalescing
the transfers in spite of the bounce buffers, or simply because of buffer
corruption. (The BT driver seems to occasionally get hit by from this too,
except that it does not trap the transfer, and the system panics later
with vm_bounce_page_free.) This "event" usually happens to me during a
savecore (on the rare occasion that a kernel coredump is actually taken
after a crash - the lack of kernel core dumps is another problem...).

bcopy:
Be smarter about handling overlapped copies and only go backwards if it
is really necessary. Going backwards on a P6 is much slower than forwards
and it's a little slower on a P5. Also moved the count mask and 'std'
down a few lines - it's a couple percent faster this way on a P5.
