Arm have recently updated that table of CPUs with extra entries (thanks for picking those up!) - but now that patch can't be easily applied to older kernels. I suspect making the reporting assuming-vulnerable may make other CPUs come out of the wood work too...
Could we avoid changing this unless we really need to?
Will / Catalin: Do either of you have an opinion here?
Is this about whether to report "vulnerable" for unknown CPUs? I think Will suggested this:

That said, some patch splitting will help to make review easier. Should such change be back-portable as well? I think so, it's not only for CPUs we'll see in the future.
