[Qemu-ppc] [PATCH v3 1/2] spapr: skip configuration section during migra

From: Greg Kurz
Subject: [Qemu-ppc] [PATCH v3 1/2] spapr: skip configuration section during migration of older machines
Date: Thu, 18 Feb 2016 12:32:18 +0100
User-agent: StGit/0.17.1-dirty

Since QEMU 2.4, we have a configuration section in the migration stream.
This must be skipped for older machines, like it is already done for x86.

This patch fixes the migration of pseries-2.3 from/to QEMU 2.3, but it
breaks migration of the same machine from/to QEMU 2.4/2.4.1/2.5. We do
that anyway because QEMU 2.3 is likely to be more widely deployed than
newer QEMU versions.
