From 437fd90c0250dee670290f9b714253671a990160 Mon Sep 17 00:00:00 2001 From: José Pekkarinen Date: Wed, 18 May 2016 13:18:31 +0300 Subject: These changes are the raw update to qemu-2.6. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Collission happened in the following patches: migration: do cleanup operation after completion(738df5b9) Bug fix.(1750c932f86) kvmclock: add a new function to update env->tsc.(b52baab2) The code provided by the patches was already in the upstreamed version.
