Thanks for catching this!

Ugh, I must have sent out a stale version of the .patch file.
My tree has the fix since I noticed it right as I was preparing to
send this out.

I have this locally:
-                          extra_qemu_params=['-M pseries', '-cpu power8'])
+                          extra_qemu_params=['-M', 'pseries', '-cpu',
'power8'])

Sent out as v2,
