Subject: [PATCH] x86/asm/entry/64: fix wrong comment.
Date: Mon, 23 Mar 2015 14:03:59 +0100
Message-Id: <1427115839-6397-1-git-send-email-dvlasenk@redhat.com>
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

The recent old_rsp -> rsp_scratch rename also changed this comment,
but in this case "old_rsp" was not referring to PER_CPU(old_rsp).

Fixing this.
