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.

5) first stage of making globals into a struct (not used yet)
The vm_allocate() call which was introduced between revisions 1.4 and
1.5 of imagact_gzip.c broke things. I have backed that out for the time
being. (Davidg: help please)
WARNING: if you have gzip enabled in your kernel, you must now run

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

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.
more weird kinds of a.out than anyone can argue for. This code failed to

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.
- Allow PPP to run multicasts natively.
- Deal properly with lots of similarly-named interfaces.
- Don't sign-extend if_flags.
NB: the last fix (to rtsock.c) must be reversed when we expand if_flags to a
reasonable size.

cleaned up much of the cruft in this thing.
No printf's in the case where things go well.
Gzip-headers can contain filenames and comments (as long as they're
shorter than the page-size.)
I don't think we leak memory, in the "exec/aout" code. I'm not quite sure
about the inflate code yet, but I don't think memory is lost.
Q: Can I add a class M_GZIP to <sys/malloc.h> and bump M_LAST one up
without any thing else needing tweaking ?

It is a non-gpl'ed "unzip" which will allow execution of a.out files which
have been sent through "gzip -9". The idea being saved disk-space.
Just now this code has quality rating: "working prototype".
To compress a file to be used with this, do it exactly this way:
gzip -9 -v < /bin/FOO > /tmp/FOO
remember to chmod /tmp/FOO as needed.
DON'T compress all of you binaries right away ! There are several things
which you should consider first:
1. Using compressed binaries, you use >MUCH< more VM, and thus swap-space.
2. It is slow.
3. It might crash your machine.

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.

a FreeBSD box to do proxy ARP as easily as most commercial routers do,
without messing around with (potentially variable) Ethernet addresses.
This code is really quite simple; I'm not at all sure why it wasn't
implemented in 4.4.
It might be worth stealing an interface flag (maybe IFF_LINK1) to use for
finer-grained control over which interfaces get proxy treatment. For the
moment, it's all or nothing.
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.
