It looks like this series is very close. Since this v10, there was some
discussion on the FPU part that seemed settled:
https://lore.kernel.org/lkml/1c2fd06e-2e97-4724-80ab-8695aa4334e7@xxxxxxxxx/

Then there was also some discussion on the synthetic MSR solution, which seemed
prescriptive enough:
https://lore.kernel.org/kvm/20240509075423.156858-1-weijiang.yang@xxxxxxxxx/

Weijiang, had you started a v2 on the synthetic MSR series? Where did you get to
on incorporating the other small v10 feedback?
