Yes, these will be for future purpose once ARMv8.4 support is added. I'd like
to keep them in this structure define since that makes iterating through the
memory mapped error records easier. Regardless of ARMv8.2 or ARMv8.4 support,
each error record in memory mapped nodes are 64 bytes apart. Having these in
the structure make the structure 64 bytes long making it possible for me to
increment through error records with the increment ++ operation.
If folks don't agree with that, I can change this structure to just have a
reserved field at the end such as:
+ u64 res0[2];
or
+ u8 res0[8];

Yes it should be! I'll add that in the next version.
