SVN rev 194459 on 2009-06-18 20:42:37Z by thompsa
Track the kernel mapping of a physical page by a new entry in vm_page
structure. When the page is shared, the kernel mapping becomes a special
type of managed page to force the cache off the page mappings. This is
needed to avoid stale entries on all ARM VIVT caches, and VIPT caches
with cache color issue.
