  Modified files:
    sys/arm/arm          pmap.c 
  Log:
  Introduce a new function, pmap_wb_page(), which check all userland mappings for
  a given page and, if the pmap is the current pmap, write back the associated
  cache line.
  Use pmap_wb_page in pmap_qenter() instead of inconditionally
  write back/invalidating the data cache.
