  Modified files:
    sys/vm               vm_mmap.c 
  Log:
  Allow non-page aligned file offset mmap's, providing that the system is
  allowed to choose the address, or that the MAP_FIXED address has the same
  remainder when modulo PAGE_SIZE as the file offset.  Apparently this is
  posix1003.1b specified behavior.  SVR4 and the other *BSD's allow it too.
  It costs us nothing to support and means we don't get EINVAL on some mmap
  code that works perfectly elsewhere.
