Yes, thanks. The patch order needs to be cleaned up. This posting was mostly
intended to try to settle the whole guest CPU feature API design. I probably
should have tagged it RFC instead of just including the coverletter blurb:
Please feel free to wait for future revisions to spend time trying to correct
smaller code issues. But I would greatly appreciate discussion on the overall
design and how we are weighing the tradeoffs for the uAPI.
