So when a hypervisor starts supporting RAPL we'll disable the driver erroneously? Isn't there any better method to detect RAPL support? So in particular in drivers/powercap/intel_rapl.c there's an enumerated list of CPU models, which is used via a x86_match_cpu() call. That's still not ideal (it does not work on hypervisors for example), but even better would be to detect RAPL support in some other fashion, that does not rely on us statically enumerating CPU models that support it.
