65	  Select this option, if you want to enable support for IO Event
66	  interrupts. IO event interrupt is a mechanism provided by RTAS
67	  to return information about hardware error and non-error events
68	  which may need OS attention. RTAS returns events for multiple
69	  event types and scopes. Device drivers can register their handlers
70	  to receive events.
71
72	  This option will only enable the IO event platform code. You
73	  will still need to enable or compile the actual drivers
74	  that use this infrastructure to handle IO event interrupts.

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