surprisingly few problems. Most fields were initialized to the
correct values by bzero(), but lk_prio was 0 instead of PINOD (=8),
the lk_wmsg was NULL instead of "ext2in", and lk_lockholder was 0
instead of -1.

consolidates some code that was starting to be duplicated in more
and more places.
Use the new function in ldconfig.
Note: I don't think that gcc should use getobjformat(), even though
it could. The compiler should limit itself to functions that are
widespread, to ease porting and cross-compilation.

- Disable the 'background' autonegotiation performed during bootstrap.
What happens currently is that the driver starts an autoneg session,
the sets a timeout in the ifnet structure and returns. Later, when the
timer expires, the watchdog routine calls the autoneg handler to check
the results of the session. The problem with this is that the session
may not complete until some point after we have started to mount NFS
filesystems, which can cause the mounts to fail. This is especially
troublesome if booting with an NFS rootfs: we need the interface up
and running before reaching the mountroot() code.
The default behavior now is to do the autoneg synchronously, i.e. wait
5 seconds for the autoneg to complete before exiting the driver attach
routine. People who want the old behavior can compile the driver with
XL_BACKGROUND_AUTONEG #defined. This has no effect on autoneg sessions
initiated by 'ifconfig xl0 media autoselect.'
This slows the probe down a little, but it's either that or botching
NFS mounts at bootup.
- If xl_setmode_mii() is called and there's an autoneg session in progress,
cancel it, _then_ set the modes.
the executable file, so it will work for both a.out and ELF format
files. I have split the object format specific code into separate
source files. It's cleaner than it was before, but it's still
pretty crufty.
Don't cheat on your make world for this update. A lot of things
have to be rebuilt for it to work, including the compiler and all
of the profiled libraries.

The change a couple of days ago to ignore these numbers in statically
configured vfsconf structs was slightly premature because the cd9660,
cfs, devfs, ext2fs, nfs vfs's still used MOUNT_* instead of the number
in their vfsconf struct.
detachment of vfs sysctls. Unloading of vfs LKMs doesn't actually
work for any vfs, since it leaves garbage pointers to memory
allocation control structures.
and use this when masking/unmasking interrupts.
Maintain a mapping from (iopaic number, int pin) tuple to irq number,
and use this when configuring devices and programming the ioapics.
Previous code assumed that irq number was equal to int pin number, and
that the ioapic number was 0.
Don't let an AP enter _cpu_switch before all local apics are initialized.
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
is participating in the experiment and has coordinated its use of
the protocol with the developer of the protocol.
