waiting for procfs to get fixed:
- Use fill_eproc() to obtain correct VM stats. Attempt to compute VmLib.
- Fill some more fields in proc/<pid>/stat, and add four (unimplemented)
fields after studying a recent Linux kernel.
- Compute CPU frequency only once instead of twice.
- Fix some comments that were OBE.
- Fix indentation except where it makes the code less readable.
- Improve the formatting for devices identified by the database.
- Fix the pcib_route_interrupt method definition, as an old version
snuck in here somehow 8(
- Remove a couple of the vendor/device IDs for PCI:ISA bridges which
correctly identify themselves.

- Move PCI core code to dev/pci.
- Split bridge code out into separate modules.
- Remove the descriptive strings from the bridge drivers. If you
want to know what a device is, use pciconf. Add support for
broadly identifying devices based on class/subclass, and for
parsing a preloaded device identification database so that if
you want to waste the memory, you can identify *anything* we know
about.
- Remove machine-dependant code from the core PCI code. APIC interrupt
mapping is performed by shadowing the intline register in machine-
dependant code.
- Bring interrupt routing support to the Alpha
(although many platforms don't yet support routing or mapping
interrupts entirely correctly). This resulted in spamming
<sys/bus.h> into more places than it really should have gone.
- Put sys/dev on the kernel/modules include path. This avoids
having to change *all* the pci*.h includes.
since ether_ifattach() does it for us. We do need to call ether_ifdetach()
instead of if_detach(). And we don't have to check for ifp->if_name
already being initialized because it never will be in FreeBSD 4.x and
above.

.PATH to ${.CURDIR}/[...]/kern , the "exists" expression will fail for the
form exists(${.CURDIR}/[...]/kern/). This appears to be happening because
make is searching for the argument to "exists" by using .PATH rather than a
relative search, because .PATH and the argument match at the beginning.
Additionally, make appears to consider a path that starts with ${.CURDIR}
as relative, even though it expands to an absolute path.
The reason that most people aren't seeing this problem is that the absolute
paths of /usr/src/sys and /sys are also searched, so as long as the kernel
source can be found in at least one of those places, no problems surface.
This problem was inadvertently introduced on 1 December 2000, with the
addition of the sysvipc modules.
calling the C functions mtx_enter_hard() and mtx_exit_hard() clobbers them.
Note that %eax is also not call safe, but it is already clobbered due to
cmpxchg. However, now we are back to not compiling again, so these macros
are still left disabled for now.
slightly more sane. Make the arguments to the nop MPASS2 match those

infrastructure. It's not perfect, but it's a lot better than what
we've been using so far. The following rules apply to this:
o BSD component names should be capitalised
o Layer names should be taken from the non-CA set for now. We
may elect to add some new BSD-specific layers later.
- Make it possible to turn off selective debugging flags or layers
by listing them in debug.acpi.layer or debug.acpi.level prefixed
with !.
- Fully implement support for avoiding nodes in the ACPI namespace.
Nodes may be listed in the debug.acpi.avoid environment variable;
these nodes and all their children will be ignored (although still
scanned over) by ACPI functions which scan the namespace. Multiple
nodes can be specified, separated by whitespace.
- Implement support for selectively disabling ACPI subsystem components
via the debug.acpi.disable environment variable. The following
components can be disabled:
o bus creation/scanning of the ACPI 'bus'
o children attachment of children to the ACPI 'bus'
o button the acpi_button control-method button driver
o ec the acpi_ec embedded-controller driver
o isa acpi replacement of PnP BIOS for ISA device discovery
o lid the control-method lid switch driver
o pci pci root-bus discovery
o processor CPU power/speed management
o thermal system temperature detection and control
o timer ACPI timecounter
Multiple components may be disabled by specifying their name(s)
separated by whitespace.
- Add support for ioctl registration. ACPI subsystem components may
register ioctl handlers with the /dev/acpi generic ioctl handler,
allowing us to avoid the need for a multitude of /dev/acpi* control
devices, etc.
that of MTX_EXIT. Don't assume that the reg parameter to MTX_ENTER
holds curproc, load it explicitly. Put semi-colons at the end of
the macros to be more consistent and so its harder to forget them
when these change.
