The recent patch to convert cell to use pci_controller_ops had a small
bug which broke machines using an iommu.
The set of phb->controller_ops was added after the check for name !=
"pci", meaning pcix/pcie PHBs weren't getting their ops set correctly.

The recent change to the EEH probing causes a crash on Cell because
eeh_ops is NULL.

You should have nothing to do, Michael has fixed it up when he merged

As Michael pointed out, create_events_from_catalog() fails when
we either have:
- a kernel bug
- some sort of hypervisor misconfiguration
- ENOMEM
In all the above cases, we can also fail 24x7 initcall.
For hypervisor errors, EIO is used so there is something reported
