Similarly to the previous Spectre patches I've applied these three KVM patches to
tip:x86/pti too, to keep them all in a single backportable group of commits. They
all look correct to me and solve real problems, and there's no conflict with
current upstream KVM code.

Let me know if that's OK to you or if you'd like to see any changes to them.

Thanks,
