Original description: Enlightened VMCS v1 definition was updates to include fields for the following features: - PerfGlobalCtrl - EnclsExitingBitmap - TSC scaling - GuestLbrCtl - CET - SSP While the information is missing in the publicly available TLFS, the updated definition comes with a new feature bit in CPUID.0x4000000A.EBX (BIT 0). Use a made up HV_X64_NESTED_EVMCS1_2022_UPDATE name for it. Add support for the new revision to KVM. SSP, CET and GuestLbrCtl features are not currently supported by KVM. While on it, implement Sean's idea to use vmcs_config for setting up L1 VMX control MSRs instead of re-reading host MSRs.
