At the moment if request_event_sources_irqs() can't allocate or request

The RAS code has a #define, RAS_VECTOR_OFFSET, that's used in the
check-exception RTAS call for the vector offset of the exception.
We'll be using this same vector offset for the upcoming IO Event interrupts

Hi Paul,
While we are at it, can we also add nop to the list of emulated
instructions?

Emulate ori 0,0,0 (nop).
The long winded way is to do:

Emulate ori 0,0,0 (nop).
Partition hibernation will use some of the same code as is
currently used for Live Partition Migration. This function
further abstracts this code such that code outside of rtas.c
can utilize it. It also changes the error field in the suspend
me data structure to be an atomic type, since it is set
Enables support for HMC initiated partition hibernation. This is
a firmware assisted hibernation, since the firmware handles writing
the memory out to disk, along with other partition information,
so we just mimic suspend to ram.

I have a patch in development that emulates most of the arithmetic,
logical and shift/rotate instructions, including ori.
