Unless I am missing something, this is just another temperature sensor.
You should just name it temp2_input; there should be no need to change the API.

I'm not very sure what you mean. Yes, it does be another sensor, but it
only can be accessed by MSR_IA32_PACKAGE_THERM_STATUS, not original
register MSR_IA32_THERM_STATUS. IMO, temp2_input should mean another
same MSR based on per CPU, but apparently, here it's not. Please fix me.
