Konstantin Belousov 2c6946dca2 When updating/accessing the timehands, barriers are needed to ensure
that:
- th_generation update is visible after the parameters update is
  visible;
- the read of parameters is not reordered before initial read of
  th_generation.

On UP kernels, compiler barriers are enough.  For SMP machines, CPU
barriers must be used too, as was confirmed by submitter by testing on
the Freescale T4240 platform with 24 PowerPC processors.
