KVM: Add MCE support
The related MSRs are emulated. MCE capability is exported via extension KVM_CAP_MCE and ioctl KVM_X86_GET_MCE_CAP_SUPPORTED. A new vcpu ioctl command KVM_X86_SETUP_MCE is used to setup MCE emulation such as the mcg_cap. MCE is injected via vcpu ioctl command KVM_X86_SET_MCE. Extended machine-check state (MCG_EXT_P) and CMCI are not implemented. Signed-off-by: Huang Ying <ying.huang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>
