With the 32 PAE build of Xen gone, 32bit PV guests' top level pagetables no longer behave exactly like PAE in hardware. They should have A/D bits set, for the same performance reasons as apply to other levels. This brings the domain builder in line with how Xen constructs a 32bit dom0. As a purely code improvement, make use of range notation to initialise identical values in adjacent array elements.
