This patch is from John Rose <johnrose@austin.ibm.com>.
EEH scans the system I/O adapters at boot for EEH-capabilities. If no
EEH-capable adapters are found, the subsystem is marked disabled for the life
of the system. EEH should allow dynamic enabling of the EEH subsystem when
hotplug-adding an adapter.
