  Move MAC check_vnode_mmap entry point out from being exclusive to
  MAP_SHARED so that the entry point gets executed un-conditionally.
  This may be useful for security policies which want to perform access
  control checks around run-time linking.
  
  -add the mmap(2) flags argument to the check_vnode_mmap entry point
   so that we can make access control decisions based on the type of
   mapped object.
  -update any dependent API around this parameter addition such as
   function prototype modifications, entry point parameter additions
   and the inclusion of sys/mman.h header file.
  -Change the MLS, BIBA and LOMAC security policies so that subject
   domination routines are not executed unless the type of mapping is
   shared. This is done to maintain compatibility between the old
   vm_mmap_vnode(9) and these policies.
