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).
