[Xen-devel] [PATCH] Fix shadow code's handling of p2m superpage changes

When a p2m superpage entry is shattered, it's important not to 
unshadow any parts of the 2MB region that are still there afterwards. 
Otherwise shattering a superpage that contains the guest's top-level
pagetable will cause the guest to be killed.
