Control) as a MAC Framework policy module. Unlike the existing
src/sys/security/lomac implementation, this one has its fingers out
of the kernel lock order and doesn't make use of flags in existing
kernel structures. This greatly reduces the quantity of replicated
code with src/sys/kern, simplifies the implementation (3000 vs 8500
lines), and correctes a number of known stability problems with
the existing LOMAC implementation, which will be removed. A bit
more hooking up to do here.

- If a PCI device is not present, then a 32-bit read_config() is going to
return 0xffffffff not 0xffff.
- For the 82454NX chipset, the MIOC that we read the bus numbers of the
various host-PCI bridges from is at function (slot) 0x10 not 0x0.

1. Detect the revision of the Rhine chip we're using.
2. Use the force reset command on revisions which support
it whenever the normal reset command fails.
This should solve a wide range of "my vr0 locks up with reset
failed messages" problems. (Although the root causes should
be eventually tracked down.)

Add function map_port_space() to map the memory mapped I/O port
range as uncacheable virtual memory and call it prior to probing
for a console. This removes the dependency on the loader to have
done this for us. Note that this change does not include doing
the same for APs.

This code allows a user program to enable target mode on a SIM and
then emulate any number of devices (disks, tape drives, etc.) All
decisions about device behavior (UA, CA, inquiry response) are left
to the usermode program and the kernel driver is merely a conduit
for CCBs. This enables multiple concurrent target emulators, each
using its own backing store and IO model.
Also included is a user program that emulates a disk (RBC) using a
file as a backing store. This provides functionality similar to
md(4) at the CAM layer.
Code has been tested on ahc(4) and should also work on isp(4) (and
other SIMs that gain target mode support). It is a complete rewrite
of /sys/cam/scsi_target* and /usr/share/examples/scsi_target.

to PCI bridge can be read be evaluating the _BBN method of the host to PCI
device. Unfortunately, there appear to be some lazy/ignorant/moronic/
whatever BIOS writers that return 0 for _BBN for all host to PCI bridges in
the system. On a system with a single host to PCI bridge this is not a
problem as the child bus of that single bridge will be bus 0 anyway.
However, on systems with multiple host to PCI bridges and l/i/m/w BIOS
writers this is a major problem resulting in all but the first host to
PCI bridge failing to attach. So, this adds a workaround.
If the _BBN of a host to PCI bridge is zero and pcib0 already exists
and is not us, the we use _ADR to look up our PCI function and slot
(we currently assume we are on bus 0) and use that to call
host_pcib_get_busno() to try and extract our bus number from config
registers on the host to PCI bridge device. If that fails, then we make
an evil assumption that ACPI's _SB_ namespace lays out the host to PCI
bridges in ascending order and use our pcib unit number as our bus
number.
