Clean up the unexpected busfree handler. We now look directly at the
message that might have caused the bus free to occur instead of looking
at an SCB flag. This makes the handling more robust and also allows for
recovery actions that might cause an "unexpected busfree" to be performed
even if an SCB is not availible to "tag". Most notably, this happens
when we don't find an SCB for a reconnecting target.
to fix a selection timeout problem.
If we can't find an SCB for the reconnecting target, issue a bus device
reset as the SCSI2 spec suggests.
Add a missing call to "add_scb_to_free_list" in the non paging case. In
the non-paging case, the SCBs don't really need to be on the free list,
but putting them there clears the tag field which is something the recovery
code depends on.

With these fixes, I was able to complete a 'make world' with remote src
and obj directories.
Delete bogus local versions of mount*.[ch] and nfs_prot*.[ch].
Use v3 protocol by default for NFS mounts. If v3 is not supported, v2 is
used automatically. Add a new mount options for NFS, 'nfsv2' to allow the
administrator to force the use of the older protocol.
Document the new mount options and fix a couple of markup problems.
1) Dell Latitude XPi
This laptop has a strange, IMHO broken :-), keyboard controller which
wouldn't disable the keyboard interrupt. The kludge is to disable tty
intr. during set_keyboard(), used for changing LED and setting
typematic.
The patch also changes the function name:
set_keyboard() -> set_keyboard_param()
Although it is a static function, the name corrides with a routine in
`syscons' and is confusing when debugging the kernel which has both
`syscons' and `pcvt' with DDB. (Suggested by Bruce)
2) doreset() bug
doreset() failed to preserve some bits in the keyboard controller's
command byte during keyboard reset. This bug may put some keyboard
controllers in old motherboards (386 and 486) in a strange state,
resulting in complete keyboard lockup or random key input.

This patch fixes the problem of vic only capturing an even or odd frame plus
the my early patch for missing frames with resolutions higher than 320x240
in rgb mode.
The yuv422 patch introduces a minor bug in that a green line appears at the
bottom of the captured window . There is no easy work around for this right
now.

is NULLVP, union node will have neither uppervp nor lowervp. This
causes page fault trap.
The union_removed_upper just remove union node from cache and it
doesn't set uppervp to NULLVP. Since union node is removed from
cache, it will not be referenced.
The code that remove union node from cache was copied from
union_inactive.
ld-specific flags. LDFLAGS is really for ld-related flags for cc,
not for ld, and some flags, e.g., -Bshareable, mean completely
different things to cc and ld. Having the wrong things in LDFLAGS
also broke the standard ${PROG} target. This was kludged around
by using a special rule that depended on LDFLAGS being bogus.
Fixing `make depend' broke the special rule but fixed the standard
rule (except in the DESTDIR case, which was handled more strictly
here than elsewhere).
VOP_LINK(). The reason of strange behavior was wrong order of the
argument, that is, the operation
# ln foo bar
in a union fs tried to do
# ln bar foo
in ufs layer.
Now we can make a link in a union fs.
fix!
The ufs_link() assumes that vnode is not unlocked and tries to lock it
in certain case. Because union_link calls VOP_LINK after locking vnode,
vn_lock in ufs_link causes above panic.
Currently, I don't know the real fix for a locking violation in
union_link, but I think it is important to avoid panic.
A vnode is unlocked before calling VOP_LINK and is locked after it if
the vnode is not union fs. Even though panic went away, the process
that access the union fs in which link was made will hang-up.
Hang-up can be easily reproduced by following operation:
mount -t union a b
cd b
ln foo bar
ls
for this is already in place, so "make tags" (or "make tags HTML=yes")
should work after your next make world.
