  Modified files:
    sys/vm               vm_map.h vm_map.c 
    sys/i386/i386        pmap.c 
  Log:
  Don't let pmap_object_init_pt() exhaust all available free pages
  (allocating pv entries w/ zalloci) when called in a loop due to
  an madvise().  It is possible to completely exhaust the free page list and
  cause a system panic when an expected allocation fails.
