From: Julien Grall <julien.gr...@linaro.org> The function domain_get_maximum_gpfn is returning the maximum gpfn ever mapped in the guest. We can use d->arch.p2m.max_mapped_gfn for this purpose.
We use this in xenaccess as to avoid the user attempting to set page permissions on pages which don't exist for the domain, as a non-arch specific sanity check.
