  SVN rev 193712 on 2009-06-08 12:15:39Z by raj
  
  Invalidate cache in pmap_remove_all() on ARM.
  
  When pages are removed from virtual address space by calling pmap_remove_all()
  CPU caches were not invalidated, which led to read corruption when another
  page got mapped at this same virtual address at later time (the CPU was
  retrieving stale contents).
