Call Logical Processor (CLP) Architecture is used for managing PCI functions on
s390x. Define and include the structures and routines needed to interact with
PCI devices during IPL.
Headers in ~/qemu/include/hw are not normally visible and must be included
using a relative path. Due to this, the QEMU_PACKED macro must also be defined
here.

I just noticed that you later remove this unused prototype for
enumerate_pci_functions() in a later patch again. Please remove it from this
patch here in the next respin instead.
Thanks,
