Hi Andre,

FnV (FAR not Valid) bit was introduced by ARMv8 in both AArch32 and
AArch64 (See D7-2275, D7-2277, G6-4958, G6-4962 in ARM DDI 0487B.a).

I understand that this just prepares the data structures for patch #14,
but I was wondering if we should update the other fields on the way as
well, for instance there is now "ar" in Aarch32 also.

I didn't want to do it because hsr_dabt will get a bit messy for AArch32. For instance bit[10] has a different meaning depending on the value of DFSC.

So if you don't mind, I would stick on FnV for now and will add the others when we really need them :).
