commit 4ad33411308596f2f918603509729922a1ec4411 upstream. It makes sense to label "Digital Thermal Sensor" as "DTS", but unfortunately the string "dts" was already used for "Debug Store", and /proc/cpuinfo is a user space ABI. Therefore, rename this to "dtherm".

2012-05-01hwmon: (coretemp) Increase CPU core limitGuenter Roeck
CPU core ID is used to index the core_data[] array. The core ID is, however, not sequential; 10-core CPUS can have a core ID as high as 25. Increase the limit to 32 to be able to deal with current CPUs.

2012-04-25hwmon: fam15h_power: fix bogus values with current BIOSesAndre Przywara
Newer BKDG[1] versions recommend a different initialization value for the running average range register in the northbridge. This improves the power reading by avoiding counter saturations resulting in bogus values for anything below about 80% of TDP power consumption. Updated BIOSes will have this new value set up from the beginning, but meanwhile we correct this value ourselves. This needs to be done on all northbridges, even on those where the driver itself does not register at. This fixes the driver on all current machines to provide proper values for idle load.
