I did that on my Cubietruck and I made the rookie mistake of not trying
a hypervisor _without_ your changes, so I don't know if this crash
(see inline) is due to your patch or something else.
Also I messed up and made the livepatch test run every time it boots, so
now it is stuck in a loop of crashes :-(
The git tree is:
git://xenbits.xen.org/people/konradwilk/xen.git staging-4.9
Stay tuned.
