Where is that patch which moves INTEL_PT ?

    Processor tracing is already enumerated in word 9 (CPUID[7,0].EBX),
    so do not duplicate it in the scattered features word.

Can KVM folks please stop doing random changes to the cpufeatures code
without talking to x86 maintainers and Borislav?

This wants to go through TIP or at least reviewed and acked.

Thanks,
