Al Viro 6a029a90f5 [PATCH] mmaper_kern.c fixes [buffer overruns]
- copy_from_user() can fail; ->write() must check its return value.

 - severe buffer overruns both in ->read() and ->write() - lseek to the
   end (i.e.  to mmapper_size) and

	if (count + *ppos > mmapper_size)
		count = count + *ppos - mmapper_size;

   will do absolutely nothing.  Then it will call

	copy_to_user(buf,&v_buf[*ppos],count);

   with obvious results (similar for ->write()).

   Fixed by turning read to simple_read_from_buffer() and by doing
   normal limiting of count in ->write().

 - gratitious lock_kernel() in ->mmap() - it's useless there.

 - lots of gratuitous includes.
