From 5d335dc7f64e2bd394c1bf86c6e5582fd859857a Mon Sep 17 00:00:00 2001
Message-Id: <5d335dc7f64e2bd394c1bf86c6e5582fd859857a@dist-git>
From: Paolo Bonzini <pbonzini@redhat.com>
Date: Tue, 12 Dec 2017 16:23:42 +0100
Subject: [PATCH] RHEL: cpu: Add downstream only CPU features for CVE-2017-5715

RHEL-only: The downstream patches for CVE-2017-5715 contained more CPU
features than what was eventually pushed upstream. We need to keep them
included for backward compatibility.
