From: Len Brown <len.brown@intel.com>
Staring in Linux-4.3-rc1, commit 6fb3143b561c ("tools/power turbostat: dump CONFIG_TDP") touches MSR 0x648, which is not supported on IVB-Xeon. This results in "turbostat --debug" exiting on those systems:
turbostat: /dev/cpu/2/msr offset 0x648 read failed: Input/output error
Remove IVB-Xeon from the list of machines supporting with that MSR.
