I'd say they are both 'cosmetic' as they don't cause guest
failure nor even warning (linux doesn't care (so far) and
we don't have windows for ARM to verify extended checksum).
So we don't have to delay release for both of them.
I assumed that Samuel, would include patches in his RSDP
refactoring series and we would merge them as whole later on.
