    Subject[PATCH v3 06/21] KVM:x86: Report XSS as to-be-saved if there are supported features
    Date
    From: Sean Christopherson <sean.j.christopherson@intel.com>

    Add MSR_IA32_XSS to the list of MSRs reported to userspace if
    supported_xss is non-zero, i.e. KVM supports at least one XSS based
    feature.
