Subject: [RFC PATCH 05/21] x86/sgx: Expose SGX architectural definitions to the kernel
Date: Fri, 26 Jul 2019 22:51:58 -0700	[thread overview]
Message-ID: <20190727055214.9282-6-sean.j.christopherson@intel.com> (raw)
In-Reply-To: <20190727055214.9282-1-sean.j.christopherson@intel.com>

KVM will use many of the architectural constants and structs to
virtualize SGX.
