[PATCH] ppc64: mark failed devices

17-eeh-slot-marking-bug.patch

A device that experiences a PCI outage may be just one deivce out
of many that was affected. In order to avoid repeated reports of
a failure, the entire tree of affected devices should be marked
as failed. This patch marks up the entire tree.
