I ask HW team about it but I have a question - has it any relationship with
replacing MIPS SYNC with lightweight SYNCs (SYNC_WMB etc)?
Of course. If you cannot explain the semantics of the primitives you
introduce, how can we judge the patch.

You missed a point - it is a question about replacement of SYNC with lightweight primitives. It is NOT a question about multithread system behavior without any SYNC. The answer on a latest Will's question lies in different area.
