I think that'll be a different format again. Perhaps a separate cpu-info
section of the file for each VCPU, within which we specify the affinity
info. I'm pretty sure we won't go for a single string with whitespace
delimiters!

Anyhow, the current patch does have flexibility in its favour, since it
supports the list format *and* the string format. So I guess it's okay
really.
