I have based this on top of pvspinlock kvm host patchset (V12) I would change the description to merely say what the CPUID bits mean, and what they mean is exactly that an MSR is valid.

Steal time is a host feature, not a guest feature: IIUC if this bit is set, the hypervisor can pass the guest information about how much time was spent running other processes outside the VM. > enabled when > + || || shedstat or task delay accounting > + || || is supported by the host.
