i'm trying to run a very simple domU kernel on Xen/x86_64, and i'm getting some trouble with update_va_mapping(): when trying to remap some page table entry, i find the virtual address still pointing to the same machine address after the return of the hypercall.

What machine page does 'cons' point at before update_va_mapping()? Is it definitely a different page?
