and some other bug fixes. I don't have a meteor RGB but I have been told
that it works.

queue type is not set to QUEUE_NONE. This appears to have
caused a hang bug that has been lurking.
2) Fix bugs that brelse'ing locked buffers do not "free" them, but the
code assumes so. This can cause hangs when LFS is used.
3) Use malloced memory for directories when applicable. The amount
of malloced memory is seriously limited, but should decrease the
amount of memory used by an average directory to 1/4 - 1/2 previous.
This capability is fully tunable. (Note that there is no config
parameter, and might never be.)
4) Bias slightly the buffer cache usage towards non-VMIO buffers. Since
the data in VMIO buffers is not lost when the buffer is reclaimed, this
will help performance. This is adjustable also.
- split driver into FreeBSD specific and camera specific portions
(qcamio.c can run in user mode, with a Linux "driver top" etc,
and qcam.c should be trivial to port to NetBSD and BSDI.)
- support for 4bppand bidirectional transfers working better
- start of interleaved data-transfers byte-stream decodes (some of this
stuff has been pulled out for the moment to make it easier to debug)
At this point, anyone who wants to port it to other platforms should feel
free to do so. Please feed changes directly back to me so that I can produce
a unified distribution.

prevent it from conflicting with other drivers (like the aic7xxx driver).
Most of the work was in spliting out common portions of the driver and
making them generic enough to be called from the eisaconf probe.
The eisaconf probe for the 3Com 3c579 and the 3c509 when in eisa
configuration mode.
aha1742.c aic7770.c bt74x.c:
Only call eisa_registerdev after the probe is successfully.
eisaconf.c:
Increase kdc->kdc_datalen during the eisa_reg* functions instead of
in the eisa_add* functions since eisa_registerdev has already been
called and we have a kdc to manipulate.

is visible to the kernel compile, and is #included by unistd.h.
Also, I missed a reference to a static int in the midst of my other diffs.
kern_fork.c: add the tiny bit of code for rfork operation.
kern/sysv_*: shmfork() takes one less arg, it was never used.
sys/shm.h: drop "isvfork" arg from shmfork() prototype
sys/param.h: declare rfork args.. (this is where OpenBSD put it..)
sys/filedesc.h: protos for fdshare/fdcopy.
vm/vm_mmap.c: add minherit code, add rounding to mmap() type args where
it makes sense.
vm/*: drop unused isvfork arg.
Note: this rfork() implementation copies the address space mappings,
it does not connect the mappings together. ie: once the two processes
have split, the pages may be shared, but the address space is not. If one
does a mmap() etc, it does not appear in the other. This makes it not
useful for pthreads, but it is useful in it's own right for having
light-weight threads in a static shared address space.

Replace "policy" by sticky "deny all" rule.
Rules have numbers used for ordering and deletion.
Remove "rerorder" code entirely.
Count packet & bytecount matches for rules.

I was not prepared to break by default.. :-)
Allow the user to nominate one of three ranges of port numbers as
candidates for selecting a local address to replace a zero port number.
The ranges are selected via a setsockopt(s, IPPROTO_IP, IP_PORTRANGE, &arg)
call. The three ranges are: default, high (to bypass firewalls) and
low (to get a port below 1024).
The default and high port ranges are sysctl settable under sysctl
net.inet.ip.portrange.*
This code also fixes a potential deadlock if the system accidently ran out
of local port addresses. It'd drop into an infinite while loop.
The secure port selection (for root) should reduce overheads and increase
reliability of rlogin/rlogind/rsh/rshd if they are modified to take
advantage of it.

to help diagnose a problem on wcarchive (where the kernel stack was
sometimes not present), but is useful in its own right since swapping
actually reduces performance on some systems (such as wcarchive).
Note: swapping in this context means making the U pages pageable and has
nothing to do with generic VM paging, which is unaffected by this option.

port addresses (even though the PC architecture doesn't support them).
Add code to limit the I/O map size based on the lowest set bit of the
address. This cures the problem with the BT946C only having a 16 bit
map register, in voiolation of the PCI specs, without giving up the
general support of >65K port regions.
