Note that to be able to apply your readonly-GDT series to the x86 tree I'll need a 
stable SHA1 to base it on.

Paolo, how stable, non-rebasing are the KVM tree commits? Once Andy's patches hit 
the KVM tree I could pull from you and order it so that I'd send it to Linus only 
after you sent your bits upstream. That would save us 3 months of patch 
propagation latency.

Or should we keep Andy's KVM patches together with the GDT patches? Either 
workflow works for me - it's your call as these are predominantly KVM changes.

Thanks,

	Ingo
