From b644653df5e25a922d5bb7d9fb9c86bfe9dda86c Mon Sep 17 00:00:00 2001
From: "Daniel P. Berrange" <berrange@redhat.com>

Subject: [PATCH] qapi: use items()/values() intead of iteritems()/itervalues()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The iteritems()/itervalues() methods are gone in py3, but the
items()/values() methods are still around. The latter are less
efficient than the former in py2, but this has unmeasurably
small impact on QEMU build time, so taking portability over
efficiency is a net win.

(cherry picked from commit 2f8480447067d6f42af52a886385284ead052af9)
[BR: BSC#1077564 - note that this patch also includes commit
ef9d9108917d6d5f903bca31602827e512a51c50 squashed in, which is how
I originally included patch. This avoids renaming of the patch queue]
