The pci_find* functions search using the following lists:
        bus->children   (for subordinate buses)
        pci_root_buses  (for all root buses)
        pci_devices     (for devices)

  This leaves one list which we can add devices to without any drivers
  finding the new devices before we've finished with them.

- initialise bus->node list head.

- pci_scan_slot will scan the specified slot, and add the discovered
  devices to the bus->devices list only.  These devices will not
  appear on the global device list, and do not show in sysfs, procfs.
  pci_scan_slot returns the number of functions found.  If you want
  to find the devices, you have to scan bus->devices and look for
  devices where list_empty(&dev->global_list) is true.

- new function "pci_bus_add_devices" adds newly discovered devices
  to the global device lists, and handles the sysfs and procfs
  stuff, making the devices available to drivers.  All our buses
  which have an empty list head are treated as "new" (since they
  are not attached to the parent buses list of children) and are
  also added.  Currently, no buses will be in this state when this
  function is called.

- new function "pci_scan_child_bus" scans a complete bus, building
  a list of devices on bus->devices only, performing bus fixups
  via pcibios_fixup_bus() and scanning behind bridges.  It does
  make devices externally visible.

- pci_do_scan_bus retains its original behaviour - ie, it scans
  and makes devices available immediately.

- Eliminate the stack allocation of a struct pci_dev, and make
  pci_scan_slot() take a bus and a devfn argument.
- Add "dev->multifunction" to indicate whether this is a multifunction
  device.
- Run header fixups before inserting the new pci device into any
  device lists or announcing it to the drivers.
- Convert some more stuff to use the list_for_each* macro(s).

- Separate out bus resource allocator (pci_bus_alloc_resource)
- Provide pci_enable_bridges to setup command register for all
  pci bridges.

The outbsync one has further changes to come in the next batch to sort
out some platforms like PPC

Also fix the irq masking bug

This switches ide-dma to ide_execute_command and makes IDE DMA also happy
when running shared IRQ

This doesn't have the new -ac testing stuff from 2.4.21pre5-ac but it
has the stuff I now trust in it. This fixes the cache flush stuff and
also means ide-disk now should be safe shared IRQ

Dave Woodhouse did this a while ago and its been kicking around in my
tree just fine. This gets rid of a lot of the init lists of functions
still left in the kernel by having an __init type array built up for the
consoles as well

We must not look for a PCI IRQ for a non native mode IDE device
We must write PCI_INTERRUPT_LINE for VIA

ALi Magik requires workarounds for TV chips
IDE controllers require proper handling in legacy mode
PXB must be disabled on C0 450NX or the IDE will corrupt memory
VIA northbridge devices require the interrupt line is written
NEC_CBUS_2/3 require ISA DMA workarounds

This chip needs latency and other setups to avoid a PCI/AGP deadlock
with tv cards

The -ldb has to be at the end sometimes
