driver. This driver overrides the probe, attach, and read_ivar methods.
If the parent bridge is an ACPI PCI bridge, then the probe routine will
match, otherwise it will fail. It tests this by seeing if it can get
the ACPI_HANDLE ivar from the bridge device.
In the attach routine, it uses pci_add_children() to add all the child
devices (but with a slightly larger ivar so it can store ACPI_HANDLE's
for child devices) and then walks through the ACPI namespace below the
bus device to cache ACPI_HANDLE's for all child devices present in the
namespace. It does this by comparing the pci slot and function to the
address encoded in _ADR of the devices in the ACPI namespace.
The read_ivar routine passes most requests off to pci_read_ivar()
and adds a new request so that the ACPI_HANDLE for a child device can
be read.
To add proper power support the power methods can be overridden as well,
but that is not currently implemented. Also, there are cases where a
device may show in the ACPI namespace as a PCI device that the PCI probe
does not find. Currently such devices are ignored.

OOP speak, you would mark these as 'protected' members. Specifically:
- Make the pcib_softc struct public so it can be used by subclasses.
- Make pcib_{read,write}_ivar(), pcib_alloc_resource(), pcib_maxslots(),
and pcib_{read,write}_config() globals that can be used by subclasses.
- Make the pcib devclass a global variable.
- Move most of the pcib_attach() function into a global
pcib_attach_common() function that can be called by the attach routines
of subclasses.
Tested on: i386, alpha, sparc64, ia64
- Make the pci devclass a global variable.
- Add child devices in pci_attach() instead of pci_probe(). Change
pci_probe() to just check for a valid bus number from the associated
bridge and return -1000 if successful. This allows subclasses of the
PCI bus driver to override the generic driver.
- Move the code to load the vendor data into its own public function.
Really though, doing this at attach is just plain wrong. This should
really be done in the module load routine instead. As a side effect,
the 'busno' variable in pci_attach() is now no longer static (minor
bug that was harmless so far.)
- Change pci_add_children() to take an extra argument that is the size of
the device info structure passed to pci_read_device() and make it public
so subclasses of the PCI bus can call it in their attach routines.
- Move the bits to attach a probed PCI child to a PCI bus into a global
pci_add_child() function. This will allow subclasses that can detect
a PCI device not found in the normal PCI probe to add those devices in
their own attach routine. (I have seen this in the ACPI tree on my
laptop for example.) As a side effect, change the static function
pci_add_resources() to get the busno, slot, and func from the passed
in dinfo structure instead of requiring them as function arguments.

LNK device (interrupt source provider sort of) is present before using it,
but the code actually tested the status (_STA) of the PCI bridge device
doing the routing, not the actual LNK device. Fix it to check the status
of the LNK device.
_BSD_CLOCKS_PER_SEC_ are not as related to stathz as I thought. So
the previous revision will only serve to unify alpha with i386 and
other architectures. This actually does introduce some binary
incompatibilities for dynamically linked programs which make use of
clock(3) and times(3).
Change _BSD_CLK_TCK_ and _BSD_CLOCKS_PER_SEC_ to match stathz. This
should result in bug for bug compatibility in staticly linked
programs and dynamicly linked programs should see an immediate
correction.

EHOSTDOWN. These are often transient errors (when the remote host
reboots, temporary network problems, etc.), and we'd rather err on the
side of caution and keep trying send messages that never arrive than
just give up.
Note that this is not an implementation of the "back-off" methods
given in the PR. Those just seem too complicated. Why not just keep
trying each time? Trying and failing doesn't really consume
significantly more resources than if we were successful for each
message.
