12c0b20fa4 x86/PCI: use dev_printk when possible
Convert printks to use dev_printk().

I converted DBG() to dev_dbg().  This DBG() is from arch/x86/pci/pci.h and
requires source-code modification to enable, so dev_dbg() seems roughly
equivalent.

8dd779b19c x86/pci: removing subsys_initcall ordering dependencies
So far subsys_initcalls has been executed in this order depending on
the object order in the Makefile:

arch/x86/pci/visws.c:subsys_initcall(pcibios_init);
arch/x86/pci/numa.c:subsys_initcall(pci_numa_init);
arch/x86/pci/acpi.c:subsys_initcall(pci_acpi_init);
arch/x86/pci/legacy.c:subsys_initcall(pci_legacy_init);
arch/x86/pci/irq.c:subsys_initcall(pcibios_irq_init);
arch/x86/pci/common.c:subsys_initcall(pcibios_init);

This patch removes the ordering dependency. There is now only one
subsys_initcall function that contains subsystem initialization code
with a defined order.

9f67fd5db5 x86/PCI: add workaround for bug in ASUS A7V600 BIOS (rev 1005)
This BIOS claims the VIA 8237 south bridge to be compatible with VIA 586,
which it is not.

Without this patch, I get the following warning while booting,
among others,

and IRQ trouble later,

| irq 10: nobody cared (try booting with the "irqpoll" option)

Now that's an VIA 8237 chip, so pirq_via586_get shouldn't be called
at all; adding this workaround to via_router_probe() fixes the
problem for me.

Amazingly I have a 2.6.23.8 kernel that somehow works fine ... I'll
never understand why.

871d5f8dd0 x86: get mp_bus_to_node early
Currently, on an amd k8 system with multi ht chains, the numa_node of
pci devices under /sys/devices/pci0000:80/* is always 0, even if that
chain is on node 1 or 2 or 3.

Workaround: pcibus_to_node(bus) is used when we want to get the node that
pci_device is on.

In struct device, we already have numa_node member, and we could use
dev_to_node()/set_dev_node() to get and set numa_node in the device.
set_dev_node is called in pci_device_add() with pcibus_to_node(bus),
and pcibus_to_node uses bus->sysdata for nodeid.

The problem is when pci_add_device is called, bus->sysdata is not assigned
correct nodeid yet. The result is that numa_node will always be 0.

pcibios_scan_root and pci_scan_root could take sysdata. So we need to get
mp_bus_to_node mapping before these two are called, and thus
get_mp_bus_to_node could get correct node for sysdata in root bus.

In scanning of the root bus, all child busses will take parent bus sysdata.
So all pci_device->dev.numa_node will be assigned correctly and automatically.

Later we could use dev_to_node(&pci_dev->dev) to get numa_node, and we
could also could make other bus specific device get the correct numa_node
too.

This is an updated version of pci_sysdata and Jeff's pci_domain patch.

b205f6b267 i386: add support for picopower irq router
Add support for PicoPower PT86C523 IRQ router to be used with the in-kernel
yenta driver for CardBus.  With this patch cardbus works on e.g.  Dell
Latitude XPi P150CD.

Initial patch for kernel 2.4 series by Sune Mølgaard
http://molgaard.org/code/linux-2.4.31-picopower.patch

Ported to 2.6.20 by Chmouel Boudjnah (http://www.chmouel.com)

Testing and confirmation that it works by Austin Acton

Cleaned up a little for inclusion in a 2.6.21-rc7 based kernel.

Added some more cleanups according to CodingStyle, as noted by
Randy Dunlap on LKML.
