hm, i think extending the already existing flags category sounds like a better solution than the separate virtual CPU flags line in /proc/cpuinfo. We already have self-invented flag entries (such as X86_FEATURE_NOPL), and adding more for virtualization would be quite natural to do, as long as it's reasonably close to the meaning of a 'CPU feature'.
Peter, what would be your preference?
It probably makes sense to separate these out as a separate word, especially if they come from the hardware in any reasonable way. But yes, adding them to the feature array makes sense.
