Some hotplug driver functions were migrated to the kernel for use by EEH
in commit 2bf6a8fa.

Previously, the PCI Hotplug module had been changed to use the new
OFDT-based PCI probe when appropriate:
5fa80fcd

When rpaphp_pci_config_slot() was moved from the rpaphp driver to the
new kernel function pcibios_add_pci_devices(), the OFDT-based probe
stuff was dropped.  This patch restores it.

Build break: Building PCI hotplug on PowerPC results in
a build break, due to failure to export symbols.

Reported today by Dave Jones <davej@redhat.com>:
drivers/pci/hotplug/rpaphp.ko needs unknown symbol pcibios_add_pci_devices

This patch fixes the break in the arch/powerpc tree.
Next patch fixes same problem in drivers/pci tree

There is code in the RPAPHP directory that is identical to this routine;
I'll be removing that code in an upcoming patch, but this patch is needed
to expose the function to make it callable.

23-rpaphp-migrate.patch (parts)

This patch moves some pci device add & remove code from the PCI
hotplug directory to the arch/powerpc/kernel directory, and cleans
it up a tad. The primary reason for this is that the code performs
some fairly generic operations that are shared with the PCI error
recovery code (living in the arch/powerpc/kernel directory).
