64	  Select this option, if you want to enable support for IO Event
65	  interrupts. IO event interrupt is a mechanism provided by RTAS
66	  to return information about hardware error and non-error events
67	  which may need OS attention. RTAS returns events for multiple
68	  event types and scopes. Device drivers can register their handlers
69	  to receive events.

113	  by allocating pages of memory and put them "on hold". This only
