type may become necessary soon. :)
Also add a couple of additional macros that NetBSD has which we don't.
Nothing in FreeBSD uses these (yet) so adding them in shouldn't hurt
anything.
to manage their own memory. Tested on my machine (make buildworld).
I've made analogous changes on the alpha, but don't have a machine
to test.

connection.
Clean up support for devices featuring the multiple target SCSI ID feature.
On aic7890/91/96/97 chips, we can now assume the target role on multiple
target ids simultaneously. Although these chips also have sufficient
instruction space to hold to support the initiator and target role at the
same time, the initiator role is currently disabled as it will conflict
(chip design restriction) with the multi-tid feature. I'll probably add
a nob to enable the initiator (there-by disabling multi-tid) some time
in the future.
Return queue full or busy, depending on the tagged nature of the incoming
request, if our command input queue fills up in host memeory.
Deal with accept target I/O resource shortages.
If we get an underrun on a transaction that wasn't supposed to transmit
any data, don't attempt to print out the S/G list. The code would
run until hitting a non-present page. (oops)
emulator so that instances can be dynamically added and removed from the
system.
Properly reference count peripheral instances so they are cleaned up when
destroyed by the control device.
Set a timeout for test unit ready commands. Before it was uninitialized
and could cause us to drop off the bus when no real timeout had occurred.
caused by temporary EDT allocations performed by controller drivers in
their interrupt routiens.
Reference count bus entries in the EDT in preparation for support for
dynamic controller arrival and departure.
Have children of the EDT hold references to their parents.
Correct routing of the XPT_IMMED_NOTIFY ccb type for use in
target mode applications.
Fix a few cases where the generation count for EDT data members was
not being updated when a modification occurred.

it up on exit. The address for attaching the emulator (path, target id,
lun) is now specified on the command line. Some attempt at cathing
signals and cleaning up target mode instances is now made.
probably always be 16 bits if they exist at all, and fusword() and
susword() are only used in i386 code, so there aren't any portability
functions with them.
numbers as chars or use bogus casts in an attempt to unmisrepresnt
them. In top, don't assume that 0xff is the only negative cpu
number when cpu numbers are (mis)represented.
compiling, since <stdio.h> correctly doesn't declare off_t although
the pseudo-prototypes for the new fseeko() and ftello() functions
use it. Handle this like the corresponding problem for va_list
versus the vprintf() family.
Fixed some English errors.
include of <sys/queue.h> in the !KERNEL case. The prerequisites
for <ufs/ufs/quota.h> were broken in Lite2 by converting some of
the kernel declarations to use queue macros without including
<sys/queue.h>. <sys/queue.h> was included in applications in
/usr/src instead. We polluted this file instead of merging the
changes in the applications.
Include <sys/queue.h> in the KERNEL case, and forward-declare all
structs that are used in prototypes, so that this file is almost
self-sufficient even in the kernel.

request for it something like it. It was poorly worded and too
far from both POSIX wording and normal (mal)practice by referring to
sysconf(_SC_NGROUPS_MAX) instead of {NGROUPS_MAX} or NGROUPS. POSIX.1
uses curly braces to mark up "symbolic constants or limits [that may
be] defined in certain headers". Since we don't document this markup,
don't use it. Just use NGROUPS_MAX.
interrupts are enabled, this kills the last "unwanted interrupts"
(and there is no ugly hacks like in the old driver to avoid them).
COmmand interrupt devices are now supported, this applies mostly
to older CDROM's and apparently also the ZIP.
Fixed problems:
Number of total sectors wrong on some older drives.
Fixed by not using the LBA size unless we know its valid.
There has also been more general code clenaups, some reorgs also.
so that non-sloppy applications can call it without using disgusting
casts to avoid warnings. The 4th arg is sort of varargs -- it must
sometimes represent a filename, sometimes a struct pointer, and is
sometimes unused. The arg type is still caddr_t in the kernel.
