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 <sys/unistd.h>, with the prototype in <unistd.h>. sys/unistd.h
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.

Close the ip-fragment hole.
Waste less memory.
Rewrite to contemporary more readable style.
Kill separate IPACCT facility, use "accept" rules in IPFIREWALL.
Filter incoming >and< outgoing packets.
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.
Code in -current & -stable is now the same.

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.

Ok bruce, this is the one you were seeing..
- Optimise the linux a.out loading and uselib system calls so they
take advantage of some of John's recent interface improvements.
Basically, this means they make far less map changes than before.
- Attempt to plug some potentially nasty kernel_map memory leaks..
- Improve support for QMAGIC libs (I only use QMAGIC (ie: a.out libraries from
the slackware 3.0 dist) but this depends on other changes to enhance
the /compat/linux support)
- uselib goes out through a single exit as part of the resource tracking
that I did when closing the resource leaks on errors. This could be
cleaner than what I did, but making a 30-deep nested if/else was not my
idea of fun, neither did I want to repeat the same code 30 times over for
each failure possibility. I guess this function needs to be split into
smaller functions to solve this.
I've been running the Linux Netscape-2.0 (with Java) to test this, and apart
from the long-standing problem with the missing scrollbars, it appears to
still work as before with ZMAGIC libs (and the leaks).. However, I've
been using it with mods for the signal trampoline code for native linux stack
frames on signals and exterminated the blasted sigreturn printf() problem,
so I can't be certain that there is not a dependency on something else.

- fill in and use ifp->if_softc
- use if_bpf rather than private cookie variables
- change bpf interface to take advantage of this
- call ether_ifattach() directly from Ethernet drivers
- delete kludge in if_attach() that did this indirectly
and rmx_recvpipe. This has no demonstrable effect on performance.

pmap_activate since it's not used anymore. Changed cpu_fork so that
it uses one line of inline assembly rather than calling mvesp() to
get the current stack pointer. Removed mvesp() since it is no longer
being used.
fixes for previous version of new pipes from Bruce Evans. This
new version:
Supports more properly the semantics of select (BDE).
Supports "OLD_PIPE" correctly (kern_descrip.c, BDE).
Eliminates incorrect EPIPE returns (bash 'pipe broken' messages.)
Much faster yet, currently tuned relatively conservatively -- but now
gives approx 50% more perf than the new pipes code did originally.
(That was about 50% more perf than the original BSD pipe code.)
Known bugs outstanding:
No support for async io (SIGIO). Will be included soon.
Next to do:
Merge support for FIFOs.

Fix a bug in bidirectional parallel port transfers, more work is still
needed here (testers welcome).
Minor cleanup.
drives require ST_Q_SNS_HLP, they also wrongly accept a blocksize of
1024 in the first place (for a QIC-150 cartridge), but complain later
about it. The hack is to only probe for 512 for them.
Reorder the entries in st_decide_mode() so that QIC >= 525 is properly
accepted as variable blocksize.
