[Qemu-devel] [PULL 33/49] i386: remove the 'INTEL_PT' CPUID bit from named CPU models |

Processor tracing is not yet implemented for KVM and it will be an
opt in feature requiring a special module parameter.
Disable it, because it is wrong to enable it by default and
it is impossible that no one has ever used it.
