My argument is simply that if TSC_AUX cannot ALWAYS
be trusted by an application, apps will NEVER trust it.
And if apps NEVER trust it, why expose it at all?
The cpu/node info is only of heuristic value anyway; it is never
trustworthy in an absolute sense. Apps just use it to try to optimise
their own memory allocation and use patterns, but they can't rely on
that info for actual correctness.
