make amd_bus a bit smaller.

We use dev_dbg() in arch/x86/pci, but there's no easy way to turn it
on.  Add -DDEBUG when CONFIG_PCI_DEBUG=y, just like we do in drivers/pci.

For intel systems with multi IOH, we should read peer root resources
directly from PCI config space, and don't trust _CRS.

add early init quirks for VisWS. This gradually turns the VISWS subarch
into a generic PC architecture.
Signed-off-by: NIngo Molnar <mingo@elte.hu>

first step: make the VISWS subarch boot on a regular PC.

We take various shortcuts for that. We copy the generic arch setup file over
into the VISWS setup file.

This is the only step that is not expected to boot on a real VISWS.

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.

This should be safe since mmconfig*.o and init.o do not contain

I moved it to a separate function which is safer.

This avoids problems with the linker reordering them and the
less useful PCI config space access methods taking priority
over the better ones.

Delete the ability to build an ACPI kernel that does
not include PCI support.  When such a machine is created
and it requires a tuned kernel, send a patch.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
