Could the cpuid-db project be helpful at some point in this regard? It
seems to have a name ("id") for each feature and a tracking of whether
each feature is exposed via cpuinfo and with what name.

Though I am not sure if it only tracks the hardware originating features
represented in cpuid or the linux defined features as well?
