Consequently, if pmap_change_attr() is applied to a virtual address range within the kernel map, then the corresponding ranges of the direct map also need to be changed. Enhance pmap_change_attr() to handle this case automatically. Add a comment describing what pmap_change_attr() does. Discussed with: jhb END
