    Maybe this fixes poll() problems/errors some people have seen on their
    machines. I am not sure if this alignment would have caused problems
    on non-ia32 architectures but it is certainly more correct now. ;-)

      Modified files:
        sys/kern sys_generic.c
      Log:
      Poll() uses the array smallbits that is big enough to hold 32 struct
      pollfd's to avoid calling malloc() on small numbers of fd's. Because
      smalltype's members have type char, its address might be misaligned
      for a struct pollfd. Change the array of char to an array of struct
      pollfd.
