09b8b5d768 Fixed linting of and compilation of the gcc byte-swapping macros
properly.  Simply don't use the gcc macros if we're not gcc, and
declare prototypes for the byte-swapping functions in case the
macro versions are not used.  The previous fix was wrong and broke
libpcap, which abuses -Dlint.

Don't pollute the namespace if _POSIX_SOURCE is defined.  This is
broken - it makes almost everything in <machine/endian.h> inaccessible
if _POSIX_SOURCE is defined, yet <machine/endian.h> is not a POSIX
header.  Other systems don't do it any better.

Removed always-false `BYTE_ORDER == BIG_ENDIAN' ifdef.

7de64ed777 Fix a bug where a program which appended many small records to a file could
wind up writing zeros instead of real data when the file is on an NFSv2
mounted directory.

While tracking this bug down, I noticed that nfs_asyncio was waking *all*
the iods when a block was written instead of just one per block.  Fixing this
gives a 25% performance improvment for writes on v2 (less for v3).

Both are 2.2 candidates.

47e567e3df Avoid `lock against myself' panic by following operation:
# mount -t union (or null) dir1 dir2
	# mount -t union (or null) dir2 dir1

The function namei in union_mount calls union_root.  The upper vnode
has been already locked and vn_lock in union_root causes above panic.

dfe4125212 No longer use AAP for queueing SCBs to the QINFIFO.
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.

5cc94ca038 Revert some changes to the selection and reselection code that were thought
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.

553a7d9d25 Incorporate kludge/fix from `syscons' ver 1.207 and 1.209.
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.

ff5e7e18c2 Do not set the uppervp to NULLVP in union_removed_upper. If lowervp
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.

071dc96075 Quick-hack to avoid `lock against myself' panic. It is not the real
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

69a13fa7d1 Fix `lockmgr: locking against myself' panic by multi union mount of
same directory pair.

If we do:
    mount -t union a b
    mount -t union a b
then, (1) namei tries to lock fs which has been already locked by
first union mount and (2) union_root() tries to lock locked fs.  To
avoid first deadlock condition, unlock vnode if lowerrootvp is union
node, and to avoid second case, union_mount returns EDEADLK when multi
union mount is detected.
