That's micro optimizing Xen... there are better (and less risky) place to look for optimization.
I would appreciate you point me those places.

Knowing how fragile the locking is on the old vGIC, the risk of micro-optimizing is not worth it. If you can provide number that shows you can improve performance by more than 10% in common case with this patch only, then I will reconsider my position.
I got it.
