and rename it to pci.c. This also required moving
arch/ppc64/kernel/pci.h into include/asm-powerpc (called
ppc-pci.h.

Complete moving arch/ppc64/kernel/mpic.h,
include/asm-ppc/reg.h, include/asm-ppc64/kdebug.h
and include/asm-ppc64/kprobes.h
Add arch/powerpc/platforms/Makefile and use it from
arch/powerpc/Makefile
Introduce OLDARCH temporarily so we can point back to
the originating architecture

This patch pulls the PCI-related junk out of struct device_node and
puts it in a separate structure, struct pci_dn. The device_node now
just has a void * pointer in it, which points to a struct pci_dn for
nodes that represent PCI devices. It could potentially be used in
future for device-specific data for other sorts of devices, such as
virtual I/O devices.

OpenFirmware marks devices as failed in the device-tree when a hardware
problem is detected. The kernel needs to fail config reads/writes to
prevent a kernel crash when incorrect data is read.
This patch validates that the device-node is not marked "fail" when
config space reads/writes are attempted.

BPA is using rtas for PCI but should not be confused by
pSeries code. This also avoids some #ifdefs. Other
platforms that want to use rtas_pci.c could create
their own platform_pci.c with platform specific fixups.
