hwmon: Remove pkgtemp driver
After the merge of pkgtemp functionality into the coretemp driver,
the pkgtemp driver is no longer necessary. Remove it.

The sensors can be in core, uncore, memory controller, or -other components in a package. The feature is first implemented in Intel Sandy -Bridge platform. - -Temperature is measured in degrees Celsius and measurement resolution is -1 degree C. Valid temperatures are from 0 to TjMax degrees C, because the actual -value of temperature register is in fact a delta from TjMax. - -Temperature known as TjMax is the maximum junction temperature of package. -We get this from MSR_IA32_TEMPERATURE_TARGET. If the MSR is not accessible, -we define TjMax as 100 degrees Celsius. At this temperature, protection -mechanism will perform actions to forcibly cool down the package. Alarm -may be raised, if the temperature grows enough (more than TjMax) to trigger -the Out-Of-Spec bit. Following table summarizes the exported sysfs files: - -temp1_input - Package temperature (in millidegrees Celsius). -temp1_max - All cooling devices should be turned on. -temp1_crit - Maximum junction temperature (in millidegrees Celsius). -temp1_crit_alarm - Set when Out-of-spec bit is set, never clears. - Correct CPU operation is no longer guaranteed. |
