Log:
  Fix ARMv6/v7 mapping's wired status.
  
  Last input argument in pmap_modify_pv() should be a mask of flags to be set.
  In pmap_change_wiring() however, the straight wired status was used, which
  does not represent valid flags (and is of type boolean).
  
  This commit fixes the issue so that wired flag is passed to pmap_modify_pv()
  properly.
