The second function is redundant?
No, it's a hook we must implement, when CONFIG_PCI_DOMAINS is enabled.
Then the other function is redundant.
No, both functions are required by the interface.
by what interface? and why, please? (instead of just stating "required")
grep for CONFIG_PCI_DOMAINS in arch code and include/linux/pci.h.
This is normal "arch" interface: you enable a define, and a group of
functions is assumed to be present. Otherwise (!defined), a set of stub
no-ops is activated for your arch.
I have implemented the [small] group of functions the code assumes to be
present, when CONFIG_PCI_DOMAINS is enabled, like all the other arches
that implement PCI domain support.
