Actually, I think making it piecemeal might be easier. As in
1). Not all of the hypercalls are going to be upstreamed.
2). It gives a nice history/idea of what is actually implemented when
seaching the code.
3). git annotate can give precise git commits for when an functionality was
added.
But maybe I am just overthinking it.
