Bug Description
[Impact]
Virtual machines on GICv3-based ARM systems cannot be saved/restored or migrated.
This feature was added in QEMU 2.10.
[Test Case]
ubuntu@grotrian:~$ sudo virsh save 7936-0 7936-0.sav
Domain 7936-0 saved to 7936-0.sav
ubuntu@grotrian:~$ sudo virsh restore 7396-0.sav
error: Failed to restore domain from 7396-0.sav
error: operation failed: job: unexpectedly failed
ubuntu@grotrian:~$ sudo tail -3 /var/log/

2017-08-10 21:26:38.217+0000: shutting down, reason=failed
[Regression Risk]
The kernel changes are restricted to ARM, minimizing the regression risk on other architectures. Other than one minor offset adjustment, all patches are clean cherry-picks from upstream. Tested on Cavium ThunderX and Qualcomm Centriq.
