Its unclear what the call to create_perdomain_mapping() is doing, but it is the sole caller which passes 0. I presume it is to allocate d->arch.perdomain_l3_pg but destroy_perdomain_mapping() doesn't free this page, so I've got no idea what the destroy call is trying to achieve. ~Andrew _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/xen-devel
