Correct.  This particular system makes no guarantees that data flushed
out through CACHE operations will not overtake subsequent uncached
stores.


Thanks for the clarification, understood.  So we only need to take care
of the order of out-bound data write transactions at the processor end,
and preceding uncached load is not required here.   Sorry for the noise.
