The storage key operations are completely seperate from the rest of the ucontrol series: - ucontrol VMs can operate without them (handled by hardware) - regular VMs can make use of them too (needed for live migration) This respin only contains the non-controversial patches. I would kindly like to ask for inclusion, I will retry on storage keys as soon as I've got a solution. so long, Carsten
