Subject: [PATCH v1 1/8] kvm:vmx  Introduce CET related VMCS field definitions.
Date:   Wed, 26 Dec 2018 16:15:25 +0800
Message-Id: <20181226081532.30698-2-weijiang.yang@intel.com>
In-Reply-To: <20181226081532.30698-1-weijiang.yang@intel.com>
References: <20181226081532.30698-1-weijiang.yang@intel.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

VMX relies on these fields to save/restore CET states for
guest and host. They are added here as VMCS placeholders
for the function.
