cd8b53ed2d Omnibus PCI commit:
o Save and restore bars for suspend/resume as well as for D3->D0
	  transitions.
	o preallocate resources that the PCI devices use to avoid resource
	  conflicts
	o lazy allocation of resources not allocated by the BIOS.
	o set unattached drivers to state D3.  Set power state to D0
	  before probe/attach.  Right now there's two special cases
	  for this (display and memory devices) that need work in other
	  areas of the tree.

Please report any bugs to me.

526b5e659d Add pci_resume() to reestablish interrupt routing after
suspend/resume.
Especially after hibernation, interrupt routing went back to initial
status on some machines.

3920999db7 Add a new PCI interface method, assign_interrupt, to determine the
interrupt to be used for a device. This is intended solely for internal
use of PCI bus implementations, and exists so that PCI bus drivers
implementing special interrupt assignment methods which require
additional work at the bus level to work right can be easily derived
from the generic driver (or any other one) without resorting to hacks.

It will be used in the sparc64 ofw_pcibus driver, which will be
committed shortly.

Make use of this method in the generic implementation, and add it to
the method table of bus drivers derived from the PCI one.

5794c59372 Move the pnp and location info into the common pci bus. Make all known
pci busses implement this.

Also minor comment smithing in cardbus.  Fix copyright to this year
with my name on it since I've been doing a lot to this file.

594b5aeb67 Use rman_get_device rather than rle->resl->r_dev.
make pci_hdrtypedata and pci_read_extcap accessible (but maybe in the end
   we'll make them private again).

1d62131385 - Make pci_load_vendor_data() static and do it during MOD_LOAD instead of
when the first PCI bus attaches.
- Create /dev/pci during MOD_LOAD as well.
- Destroy /dev/pci during MOD_UNLOAD (not that you can kldunload pci, but
  might as well get the code right)

42dbeaee02 Various changes to make it easier to subclass the PCI bus device.
- 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.

Tested on:	i386, alpha, ia64, sparc64

7ba175ac23 Use the pci.c code wherever possible, rather than copying all the pci
code into cardbus and s/pci/cardbus.  This exposes a few pci_*
functions that are now static.

This work is similar to work Justin posted to the mobile list about a
year or two ago, which I have neglected since then.

This is a subset of his current work with the multiple inheritance
newbus architecutre.  When completed, that will eliminate the need for
pci/pci_private.h.

Similar work is needed for the cardbus_cis and pccard_cis code as well.
