[PATCH] allow dynamic enablement of EEH

[John Rose]

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.

Please apply, if appropriate.

Thanks-
John
