(Boris Petkov) * (Patch 1) Move msr_ia32_feature_control from nested_vmx to vcpu_vmx, because it does not depend only on nested after this patch series. (Radim Krčmář) * (Patch 2) Add a valid bitmask for MSR_IA32_FEATURE_CONTROL to allow checking individual bits of MSR_IA32_FEATURE_CONTROL according to enabled features. (Radim Krčmář) * Move the common check in handling MSR_IA32_MCG_EXT_CTL to function vmx_mcg_ext_ctl_msr_present. (Radim Krčmář) Changes in v1: * Change macro KVM_MCE_CAP_SUPPORTED to variable kvm_mce_cap_supported. * Include LMCE capability in kvm_mce_cap_supported only on Intel CPU, i.e. LMCE can be enabled only on Intel CPU. * Check if LMCE is enabled in guest MSR_IA32_FEATURE_CONTROL when handling guest access to MSR_IA32_MCG_EXT_CTL. This patch series along with the corresponding QEMU patch series (sent via another email with title "[PATCH v4 0/3] Add QEMU support for Intel local MCE") enables Intel local MCE feature for guest. This KVM patch handles guest access to LMCE-related MSR (MSR_IA32_MCG_EXT_CTL and MSR_IA32_FEATURE_CONTROL).
