Subject: [PATCH 2/4] tools/power turbostat: IVB Xeon: fix --debug regression
From: Len Brown <len.brown@...el.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.
