Subject: [PATCH] KVM: nVMX: expose "load IA32_PERF_GLOBAL_CTRL" controls
Date:   Thu, 21 Nov 2019 15:29:17 +0100
Message-Id: <1574346557-18344-1-git-send-email-pbonzini@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

These controls were added by the recent commit 03a8871add95 ("KVM:
nVMX: Expose load IA32_PERF_GLOBAL_CTRL VM-{Entry,Exit} control",
2019-11-13), so we should advertise them to userspace from
KVM_GET_MSR_FEATURE_INDEX_LIST, as well.
