These series enable TOPOEXT feature on AMD CPU. These are required to support hyperthreading on kvm guests. Stanislav Lanci posted few patches earlier. https://patchwork.kernel.org/patch/10040903/ Rebased his patches with few changes. 1. Spit the patches into two, separating cpuid functions 0x8000001D and 0x8000001E (Patch 2 and 3). 2. Removed the generic non-intel check and made a separate patch with some changes(Patch 5). 3. Fixed L3_N_SETS_AMD(from 4096 to 8192) based on CPUID_Fn8000001D_ECX_x03. Added 2 more patches. Patch 1. Fixes cache associativity. Patch 4. Adds TOPOEXT feature on AMD EPYC CPU.
