Thomas Gleixner 5412910487 rseq: Expose lightweight statistics in debugfs 
Analyzing the call frequency without actually using tracing is helpful for
analysis of this infrastructure. The overhead is minimal as it just
increments a per CPU counter associated to each operation.

The debugfs readout provides a racy sum of all counters.
