  Log:
  SVN rev 195693 on 2009-07-14 19:45:36Z by jhb
  
  - Change mmap() to fail requests with EINVAL that pass a length of 0.  This
    behavior is mandated by POSIX.
  - Do not fail requests that pass a length greater than SSIZE_MAX
    (such as > 2GB on 32-bit platforms).  The 'len' parameter is actually
    an unsigned 'size_t' so negative values don't really make sense.
