I'm guessing not, and that causes pci.h to not define pci_dev_to_eeh_dev(). Gavin, I think this is broken by your 39baadbf36cee3ede5fdb8a34006d9109e5e2570. Probably need a wrapper for pci_dev_to_eeh_dev() when !CONFIG_EEH? Actually, looking at it more, eeh_dev, which is protected by CONFIG_EEH in arch/powerpc/include/asm/eeh.h won't be defined in such situations and is the type of the return from pci_dev_to_eeh_dev(). So that's going to be broken completely if !CONFIG_EEH as above. So maybe the callers should be EEH-unaware (as they were before) and the callee becomes of the EEH variety (at compile-time) if CONFIG_EEH is set?
