With a server hat on...

There are many ARMv8 server platforms that do 64b today, but future
designs are likely to head toward 128b (for a variety of reasons). Many
of the earlier designs were 64b because that's what certain other arches
were using in their server cores. I doubt Vulcan will remain a unique
and special case for very long. On the CCIX side of things, I've been
trying to push people to go with 128b lines in future designs too.
