Hi all,

It looks like get_page_from_gva intermittenly fails on the Arndale (see [1])
leading to Dom0 crashing.

At the moment it is a bit hard to know why given the hypervisor does not
provide much information.

This series add more debug in get_page_from_gva to hopefully narrow down
the issue.

I think the 2 patches are good candidate for Xen 4.10 as this may help fixing
a dom0 crash on the Arndale.

Cheers,
