[PATCH 06/12] PCI Hotplug: make cpcihp driver use modern apis
From: Greg Kroah-Hartman
Date: Thu Feb 14 2008 - 19:45:24 EST
This removes the depandancy of the cpcihp driver from the PCI_LEGACY
config option by removing its usage of the pci_find_bus() function.

Say Y here if you have a CompactPCI system card that exposes the #ENUM
hotswap signal as a bit in a system register that can be read through
