preserve some quoting information in order to avoid removing

Don't try to extend the mapping in place if it is too short.
There's no guarantee it will be possible. Remap the file instead.
Put in a few style fixes.

generating a trap 12 panic. The code blindly assumed that in the event
of a transmit error, the packet that caused the error would still be
at the head of the driver's transmit queue (sc->xl_cdata.xl_tx_head).
However in the case of error 82 (which indicates that a transmit error
occurred after part of the transmit FIFO memory has been reclaimed)
this is not true: the TX queue has already been flushed, and the
pointer to the head of the queue is NULL, so trying to dereference
the pointer to find the transmit descriptor address causes a crash.
The code now checks for a NULL pointer before trying to reload the
chip's download pointer register. There may still be error messages
printed warning of the transmit error, but no panic should occur.
Note that this eror code is only generated with "cyclone" chipsets
(3c900B, 3c905B, and presumeably the 3c980 server adapter). It should
only appear during periods of heavy traffic, probably only on
non-switched networks.

4.1.4. Experimental Protocol
A system should not implement an experimental protocol unless it

the protocol with the developer of the protocol.

Ensure that three of the structures are the size that binutils writes
them. I just love code that doesn't share header files to avoid
problems like these.

least 2 version numbers. This fixes the bug where the dynamic
linker would try to load an ELF shared library if it found one.
Note, this change also fixes the same thing in "ld", because the
code is shared.
For "ld" there is still a problem with ".a" libraries, which cannot
be distinguished by name. I haven't decided what, if anything, to
do about that.
type numbers in vfs attach order (modulo incomplete reuse of old
numbers after vfs LKMs are unloaded). This requires reinitializing
the sysctl tree (or at least the vfs subtree) for vfs's that support
sysctls (currently only nfs). sysctl_order() already handled
reinitialization reasonably except it checked for annulled self
references in the wrong place.
Fixed sysctls for vfs LKMs.
when nfs is an LKM. Declare it in a header file. Don't forget to use
it in non-Lite2 code. Initialize it to -1 instead of to 0, since 0
will soon be the mount type number for the first vfs loaded.
NetBSD uses strcmp() to avoid this ugly global.
Our write protection of the kernel text on i386's doesn't actually
work in many cases:
- use of the 4MB page completely breaks it.
- CR0_WP isn't set until just before init is started, so the kernel
text is not write protected during kernel initialization.
device drivers about sectors no longer in use.
Device-drivers receive the call through d_strategy, if they have
D_CANFREE in d_flags.
This allows flash based devices to erase the sectors and avoid
pointlessly carrying them around in compactions.

>decision is, I'll respect it.
Another chance to architect people's principles...I can hardly wait. Seems
quite appropriate for a Sunday - I just need to get one of those collection
plates (and money envelopes) so I can profit, too. :-)
Tcl stays in /usr/src for now, but it needs to be kept up to date; same
for perl. If Jordan doesn't have "setup" (written in tcl) ready for 3.0,
then tcl will be yanked prior to the 3.0 release (and made into a port).
As for the ports tree only supporting the last FreeBSD release, this seems
sensible to me. The "ports" have always been a moving target between releases
and the problem is only going to get worse when we expand to supporting other
processor architectures. In any case, Satoshi is and always has been in charge
of the ports tree and whatever he wants to do with it (within reason :-)) is
his decision.
Does this cover the issue completely? I admit to deleting messages in this
thread with unusual fervor (people have FAR too much time on their hands!).
There's a fair bit of reasoning behind the above, but since everyone is sick
of arguing about this, I'll spare you the analysis.

to think you're using aout otherwise (and emits a rather confusing and
inaccurate diagnostic about OBJFORMAT being set in /etc/make.conf when
it most demonstrably is not set there).
a different file than the a.out hints, namely, "/var/run/ld-elf.so.hints".
These hints consist only of the directory search path. There is
no hash table as in the a.out hints, because ELF doesn't have to
search for the file with the highest minor version number. (It
doesn't have minor version numbers at all.)
A single run of ldconfig updates either the a.out hints or the ELF
hints, but not both. The set of hints to process is selected in
the usual way, via /etc/objformat, or ${OBJFORMAT}, or the "-aout"
or "-elf" command line option. The rationale is that you probably
want to search different directories for ELF than for a.out.
"ldconfig -r" is faked up to produce output like we are used to,
except that for ELF there are no minor version numbers. This should
enable "ldconfig -r" to be used for checking LIB_DEPENDS in ports
even for ELF.
I implemented the ELF functionality in a new source file, with an
eye toward eliminating the a.out code entirely at some point in
the future.
