Xen devel - Apr 2008 - Is global mapping optimization applied to current Xen?

Hi,

I''m wondering if ''global mapping page table''
optimization is applied to
current Xen source.
This technique is introduced in "Optimizing network virtualization in Xen,
Usenix 2006"
and preserves global page table mappings of a guest kernel before next
domain switching.

Thanks in advance.
