Where is that patch which moves INTEL_PT ?

commit 632218d8dee296c8b397c13b7b3b4be090a1c043

    x86: cpufeature: move processor tracing out of scattered features
    
    Processor tracing is already enumerated in word 9 (CPUID[7,0].EBX),
    so do not duplicate it in the scattered features word.
    
    Signed-off-by: Paolo Bonzini <pbonzini@...hat.com>

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,
