Steven Rostedt (Google) 869aee35cf ring-buffer: Have rb_time_cmpxchg() set the msb counter too 
commit 0aa0e5289cfe984a8a9fdd79ccf46ccf080151f7 upstream.

The rb_time_cmpxchg() on 32-bit architectures requires setting three
32-bit words to represent the 64-bit timestamp, with some salt for
synchronization. Those are: msb, top, and bottom

The issue is, the rb_time_cmpxchg() did not properly salt the msb portion,
and the msb that was written was stale.
