This series adds the support for following features in qemu. 1. RAS feature bits (SUCCOR, McaOverflowRecov) 2. perfmon-v2 3. Update EPYC-Genoa to support perfmon-v2 and RAS bits 4. Support for bits related to SRSO (sbpb, ibpb-brtype, srso-user-kernel-no) 5. Added support for feature bits CPUID_Fn80000021_EAX/CPUID_Fn80000021_EBX to address CPUID enforcement requirement in Turin platforms. 6. Add support for EPYC-Turin.
