2012-01-26X86: Introduce HW-Pstate scattered cpuid featureThomas Renninger
It is rather similar to CPB (boot capability) feature and exists since fam10h (can be looked up in AMD's BKDG). The feature is needed for powernow-k8 to cleanup init functions and to provide proper autoloading matching with the new x86cpu modalias feature.

2010-09-24x86/hwmon: fix initialization of coretempJan Beulich
Using cpuid_eax() to determine feature availability on other than the current CPU is invalid. And feature availability should also be checked in the hotplug code path.

The recently updated CPUID specification names new SVM feature bits. Add them to the list of reported features. Signed-off-by: Andre Przywara <andre.przywara@amd,com> LKML-Reference: <1283778860-26843-5-git-send-email-andre.przywara@amd.com> Signed-off-by: H. Peter Anvin <hpa@linux.intel.com>
2010-07-30x86, cpu: Package Level Thermal Control, Power Limit Notification definitionsFenghua Yu
Add package level thermal and power limit feature support. The two MSRs and features are new starting with Intel's Sandy Bridge processor. Please check Intel 64 and IA-32 Architectures SDMV Vol 3A 14.5.6 Power Limit Notification and 14.6 Package Level Thermal Management. This patch also fixes a bug which defines reverse THERM_INT_LOW_ENABLE bit and THERM_INT_HIGH_ENABLE bit.

2010-07-19x86, cpu: Split addon_cpuid_features.cH. Peter Anvin
addon_cpuid_features.c contains exactly two almost completely unrelated functions, plus has a long and very generic name. Split it into two files, scattered.c for the scattered feature flags, and topology.c for the topology information. Signed-off-by: H.
