    sys/i386/i386        tls.c 
  Log:
  Allow an info.size field of -1 to indicate that the descriptor should map
  the entire address space, requires for direct-tls %gs:OFFSET support (where
  the OFFSET is negative).  Otherwise the descriptor only maps the specified
  range (typically just the TCB area created by the thread library) and %gs:0
  must be used to obtain a pointer from which negative relative memory accesses
  can be made.
