only fault of interest that wouldn't be already counted in v_trap is a VM

some that were done wrong. They are all almost correct now...just a few
minor ones left to fix.

was discovered by John Hood who also provided this fix - which is a
rewrite of the routine (and is easier to understand than the code I wrote).

This is the main files for the iBCS2 emulator. It can be use
compiled into the kernel by using:
options IBCS2
options COMPAT_IBCS2
or as a lkm module using:
options COMPAT_IBCS2
and then loading it via the ibcs2 script in /usr/bin
REMEMBER: this code is still experimental ! NO WARRENTY !

Fix endless loop in siopoll() for an event on a tty with no tty struct.
Don't generate unwanted interrupts in the serial console driver. These
bugs probably don't matter unless the tty struct is dynamically allocated.
Support polled mode. To use it, leave out the irq and the vector in
the config file. It only causes extra overhead for open polled ports.
The maximum usable speed is approximately 1000 bps for a 16450 and
15000 bps for a 16550.
Other cosmetic changes.
Bug fixed, that caused system hang on first interrupt on some motherboards.
New version of PCI bus configuration code, now supports dynamic interrupt
configuration (using BIOS supplied values).
NCR SCSI and DEC Ethernet driver patched to use this feature.
*** Remove PCI IRQ specifications from your kernel config file ! ***
"APM" macro.
machdep.c: Made the APM-descriptors unconditional.
Bruce: if these still conflict with your debugger, please put in a reservation
for your debugger. These three desc. can be anywhere, as long as they are
contiguous, so just move them as needed.
pmap.c: tons of unused vars zapped, various other warnings silenced.
trap.c: unused vars zapped.
vm_machdep.c: A wrong argument, which by chance did the right thing, was
corrected.
the first place was so that BPF could grok trailer packets. I've since
decided that this is a job for tcpdump to decipher (if at all). Also
fixed up checks for received packet length to better cope with ancient
starlan boards.

WARNING: might hide some bug below! I commit this to improve the stability
of 2.0.

I have been running a kernel with this change since October 4th; barring
unrelated network router troubles, the pitiful little machine has
completed several builds without any interaction from me, and continues
to chug along.
I re-read wd.c, and added appropriate printfs() to look for references
to dk_badsect[]. My changes should have printed something when dk_badsect[]
was referenced.
I got no output :-(
Thus, I'm forced to concluded that something else is examining some
spurious memory... which happened to be in dk_badsect[] of the disk structure
in wd.c. I can find no other explanation of why this unnecessary
initialization causes things to operate correctly.
On the premise that such an initialization isn't going to hurt anything,
I'm going to suggest it go into 2.0.
I'd like to thank everyone for there assistance, particularly David,
John and Bruce.
been relocated to run in the 64k segment at 0x10000 with the stack at
the top of this segment. This corrects the problems machines with 512K
base memory had booting.
2. startprog routing rewritten to convert the BOOTSEG ss to a KERNELSEG
ss, this eliminated the last of the >512K memory references. Additional
cleanup in here included a better way to copy the arguments to the
kernel stack.
3. Elimination of argv and esym cruft saved a few bytes.
4. Only need to truncate the head.a_entry to a meg boundary once intead
of every time we used it! [Saving more bytes].
5. Addition of version 1 bootinfo structure support. These boot blocks
pass the kernel name in to the kernel now.
6. Removed historical comments about MACH argv stuff, as it is useless now.
that and when it does it will be done differently.
2. The kernel now does a frame setup on entry so it ``looks'' like a
real function call. This will be needed by future boot code and
debuggers.
3. Clean up stack offsets to all be in decimal and use %ebp when copying
parameters in from the boot code.
4. Implement version 1 of the uniform boot code passing mechanism with
support for kernelname passing and nfs_diskless structure passing.
5. Document the 3 different ways the kernel is called depending on what code
is calling it.

New AMD family ethernet driver. Should support BICC,NE2100, TNIC,
AT1500 and anything else that uses a Lance/PCnet type chip. Only been
tested with the BICC so far though.
Still work to do on performance and MULTICAST support needs to be added
but it's basically working and I want the revision history from this
point on

must #define NFS before including <sys/mount.h> to pick up some of
the definitions needed for struct diskless. Be sure to undef it after this
so you do not effect other code.
This is kinda sick, but it does the job. Problem found by davidg.
2. Clean up the .S files to use /* */ style comments.
This is a totally cosmetic change, not one byte of the resulting boot
code changes. But at least it is installed with correct owners and in
the right places, and gets recompiled correctly when things change!
2. New detection code so we know what boot code called us.
3. Remove old DISKLESS support code and halt if we are called by that boot
code as it will NOT work with the new nfs_diskless structure.
This is really in preperation for new boot code and new diskless support.

I think I have narrowed this down to the stack being overflown. I have
taken the push/pop of %fs out, it shouldn't be needed anyway, but the
real & correct solution might to save the registers on the stack in
locore.s before calling this stuff.
NOTE: 2.9 is backwards compatable with programs compiled with older
soundcard.h, but new programs compiled with 2.9 will not work on pre-2.9
sound drivers.
New version with improved support for WIDE SCSI using the NCR 53c825.
Test for buggy secondary cache implementations.
PCI Int to IRQ mapping now specified per slot.
improvements from 1.1.5.1. I tried to compile a kernel without BOUNCE_BUFFERS
with the previous version for my Bt946c and it puked and died. Bringing
these enhancements back in allows the faster controllers to DTRT while
still not messing up the older ISA/broken VLB controllers, since
bounce-buffering is still the default. In theory, anyway. Bt445S and Bt545S
folks should start testing this ASAP! (actually, Bt445C and Bt545C folks
even more so!).

were sometimes misaligned.
cycles. While waiting there I added a lot of the extra ()'s I have, (I have
never used LISP to any extent). So I compiled the kernel with -Wall and
shut up a lot of "suggest you add ()'s", removed a bunch of unused var's
and added a couple of declarations here and there. Having a lap-top is
highly recommended. My kernel still runs, yell at me if you kernel breaks.
This is needed for having the fdformat program no longer searching
non-public include paths.
Protect the definitions in fdreg.h against double inclusion.
more work required to grab all fonts
2)Make standard VGA font as default, make HARDFONTS an option
(load iso8859 fonts instead)
3)Check fonts_loaded for all restore (copy_font...palette)

- Make a number of filesystems work again when they are statically compiled
(blush)
- FIFOs are no longer optional; ``options FIFO'' removed from distributed
config files.
