I have added a new option -p to the mount command. This was
inspired by SunOS version of mount which uses option -p to
indicate that the mount information should be printed in fstab
format.
This is a neat way to create a new fstab file to use later when
one has modified the mount points or mount options or added or
removed mount some mount points. You just type
mount -p > /etc/fstab.new
and there is your new fstab file ready to be used though you
will of course have to add any necessary noauto flags manually.
[Committers note: This also seems to do the wrong thing for AMD
mounts, but in the more average case this is a nifty feature nonetheless
and one can always edit the bogus entries out]
Replace the annoying calls to Debugger() by panic()'s in the
#ifdef DIAGNOSTIC case, and a warning only otherwise.
People who want them to break into the debugger can always set the
breakpoint explicitly. The existing behaviour was a misfeature from
the beginning, in the (wrong) assumption that the SCSI controller must
always be of essential importance to the entire system.
Major cleanup of the timerX_{acquire,release} stuff. In particular,
make it more intelligible, improve the partially bogus locking, and
allow for a ``quick re-acquiration'' from a pending release of timer 0
that happened ``recently'', so it was not processed yet by clkintr().
This latter modification now finally allows to play XBoing over
pcaudio without losing sounds or getting complaints. ;-) (XBoing
opens/writes/closes the sound device all over the day.)

Check for, and disallow, duplicate tags in the "cvs import" command.
RCS cannot deal with duplicate tags; the extra one always becomes
inaccessible and useless.
This will prevent the common mistake of specifying the same name
for the vendor tag and the release tag. The FreeBSD CVS repository
already contains zillions of files with this error. We don't need
any more of them.

Last night (local time :) I accidently checked in an intermediate version
of this patch, which had not actually been reviewed by Joerg or Paul!
(I'll better stop committing files after midnight ...)
I'm now commiting the latest code, which has been reported to work.
Minor correction to the previous commit message for this file:
The first PCI Lance in a system will get a name of lnc1, the second
will be known as lnc2 and so on. An arbitrary number of cards is
supported in a system ...
Add interrupt register set up with original register value
before attaching. Without this fix, 3c579(EISA) never make
any H/W inturrupt.

FINALLY: PCI support for the Lance Ethernet driver.
This code applies to several systems with integrated Ethernet
chip, for example from HP or Compaq. It should also support
PCI Ethernet cards based on the AMD PCI Lance chip.
This code has been reviewed (visually) by Paul Richards and
tested (using an ISA Lance board) by Joerg Wunsch.
Since the parameters to nearly each and every single function
had to be changed (generally from unit number to lnc_soft*),
there is some potential for buglets having crept in ...
BEWARE: If you had lnc0 configured to have the ISA probe find
your PCI Lance, then it should now be found by the PCI probe,
and should be automatically configured as pci1 (!!! note the "1").
Second part of the timezone code import for version 96h. This includes
a number of bug fixes to the compiler (which bugs would previously
have caused undesirable behavior during transition times).
Merge the recently-imported tzcode96h distribution (libc portion). The
part that does zic(8)/zdump(8) is still yet to be imported (but the old
zic and zdump will work just fine with these header files and the
data format has not changed).
Import the 96h release of ADO's timezone code. This release is
primarily bugfixes, but is also contains a disclaimer of copyright.
As we are completely off the vendor branch here, this import has
no effect on the source tree.

Yet^2 another fix for the line continuation bug.
The fundamental problem with the original code is that it accesses
p[-2] which is one before the beginning of the input buffer for
empty lines. rev.1.6 just moved the problem from failures when
p[-2] happens to be '\\' to failures when it happens to be '\0'.
rev.1.5 was confused about the trailing newline and other things.
I went back to rev.1.5 and fixed it. The result is the same as
Keith Bostic's final version in PR 1356 except it loses more
gracefully for excessively long input lines.

Various fixes from frank@fwi.uva.nl (Frank van der Linden) via
rick@snowhite.cis.uoguelph.ca:
1. Clear B_NEEDCOMMIT in nfs_write to make sure that dirty data is
correctly send to the server. If a buffer was dirtied when it was in
the B_DELWRI+B_NEEDCOMMIT state, the state of the buffer was left
unchanged and when the buffer was later cleaned, just a commit rpc was
made to the server to complete the previous write. Clearing
B_NEEDCOMMIT ensures that another write is made to the server.
2. If a server returned a server (for whatever reason) returned an
answer to a write RPC that implied that fewer bytes than requested
were written, bad things would happen.
3. The setattr operation passed on the atime in stead of the mtime to
the server. The fix is trivial.
4. XIDs always started at 0, but this caused some servers (older DEC
OSF/1 3.0 so I've been told) who had very long-lasting XID caches to
get confused if, after a reboot of a BSD client, RPCs came in with a
XID that had in the past been used before from that client. Patch is
to use the current time in seconds as a starting point for XIDs. The
patch below is not perfect, because it requires the root fs to be
mounted first. This is because of the check BSD systems do, comparing
FS time to system time.

In _yp_dobind(), if we find ourselves required to contact the local ypbind
directly in order to obtain binding information, check that the local
ypbind is using a reserved port and return YPERR_YPBIND if it isn't.
We should not trust any ypbind running on a port >= IPPORT_RESERVED;
it may have been started by a malicious user hoping to trick us into
talking to a bogus ypserv.
Note that we do not check the ypserv port returned to us from ypbind.
It is assumed that ypbind has already done a reserved port test (or not,
depending on whether or not it was started with -s); if we trust the
authenticity of the local ypbind, we should also trust its judgement.

Enable transmit complete interrupt...
(author's explaination):
Bit 15 is the flag to request a transmit complete interrupt. The
driver was apparently written to minimize interrupts, and if not for a
3-COM design quirk, everything would be just ducky.
Prior to loading the outbound packet into the FIFO, the driver checks
to see if there's enough space to contain the packet. If not, the
driver requests a transmit-available interrupt when there is
sufficient room. Unfortunately, the card is continuing to process the
prior FIFO, and by the time the driver sets the threshold for a
transmit available interrupt, the space is already available. When
this occurs, the 3COM card ignores the interrupt request, and the
driver is hung waiting for an interrupt that will never occur.
There's probably a more elegant solution, but requesting the transmit
complete interrupt was the easiest to implement. An alternative fix
might be to check free FIFO space again, after requesting the transmit
available interrupt, but I haven't bothered pursuing this. Since the
patch, my 3C590 (PCI, same FIFO interface as 3C509) has been rock
solid.
Back out my change for Peter which did transfer timings based on current
chunk rather than distribution - it's just caused the numbers to fluctuate
too wildly, sorry Peter! ;-(
