SVN rev 180845 on 2008-07-27 17:32:36Z by alc
Enhance pmap_change_attr(). Use pmap_demote_pde() to demote a 2MB page
mapping to 4KB page mappings when the specified attribute change only
applies to a portion of the 2MB page. Previously, in such cases,
pmap_change_attr() gave up and returned an error.
