| | | | | | | | | | | | | | Further relax temperature range checks after reading the IA32_TEMPERATURE_TARGET register. If the register returns a value other than 0 in bits 16..32, assume that the returned value is correct. This change applies to both packet and core temperature limits.

* hwmon: (coretemp) Fix TjMax detection for older CPUsGuenter Roeck2011-06-01
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit a321cedb12904114e2ba5041a3673ca24deb09c9 excludes CPU models 0xe, 0xf, 0x16, and 0x1a from TjMax temperature adjustment, even though several of those CPUs are known to have TiMax other than 100 degrees C, and even though the code in adjust_tjmax() explicitly handles those CPUs and points to a Web document listing several of the affected CPU IDs.

* hwmon: (abituguru) Depend on DMIJean Delvare2011-05-25
| | | | | | | | | | | | | | | | | The abituguru drivers are only built on X86, where DMI support is now enabled by default. So let these drivers depend on DMI, for the following gains: * Robustness and safety. Detection of these devices is weak and uses non-standard methods, it should really be limited to Abit boards unless the user explicitly asks otherwise. * Code simplicity. The code is easier to read without ifdefs. * Better build testing coverage. Now there's only one way to build the drivers, so no risk of build failure on exotic systems.
