What are the numbers without Xen?
Good question. Didn't try. At least putchar should be implemented for that.

Which version of Xen are you using?
This morning's staging, commit-id 58eb90a9650a8ea73533bc2b87c13b8ca7bbe35a.

This also tells you that in the trap case the vGIC is not the bigger overhead.
Indeed, not the bigger. But significant even in this trivial case (receiving an 
interrupt twice a second).

This is with all your series applied but [4], correct?

Did you try to see the perfomance improvement patch by patch?
No. Not yet.
