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

13 | Description | ||
14 | ----------- | ||
15 | |||
16 | This driver permits reading package level temperature sensor embedded inside | ||
17 | Intel CPU package. The sensors can be in core, uncore, memory controller, or | ||
18 | other components in a package. The feature is first implemented in Intel Sandy | ||
19 | Bridge platform. | ||
20 | |||
21 | Temperature is measured in degrees Celsius and measurement resolution is | ||
22 | 1 degree C. Valid temperatures are from 0 to TjMax degrees C, because the actual | ||
23 | value of temperature register is in fact a delta from TjMax. | ||
24 | |||
25 | Temperature known as TjMax is the maximum junction temperature of package. | ||
26 | We get this from MSR_IA32_TEMPERATURE_TARGET. If the MSR is not accessible, | ||
27 | we define TjMax as 100 degrees Celsius. At this temperature, protection | ||
28 | mechanism will perform actions to forcibly cool down the package. Alarm | ||
29 | may be raised, if the temperature grows enough (more than TjMax) to trigger | ||
30 | the Out-Of-Spec bit. Following table summarizes the exported sysfs files: | ||
31 | |||
32 | temp1_input - Package temperature (in millidegrees Celsius). | ||
33 | temp1_max - All cooling devices should be turned on. | ||
34 | temp1_crit - Maximum junction temperature (in millidegrees Celsius). | ||
35 | temp1_crit_alarm - Set when Out-of-spec bit is set, never clears. | ||
36 | Correct CPU operation is no longer guaranteed. | ||
