Similar to the PASSTHROUGH_F() thing in the first patch, these aren't strictly
being passed through. In practice, they are passed through as of the current
code base due to the features residing in KVM-only words, but I'd like to avoid
stating that features are being passed through unless KVM very deliberately wants
to ignore the kernel.
As before, I'll tweak when applying. Same goes for patches 3 and 4.
