Changes in this cycle were:
- Add the "ratelimit:N" parameter to the split_lock_detect= boot option,
to rate-limit the generation of bus-lock exceptions. This is both
easier on system resources and kinder to offending applications than
the current policy of outright killing them.
- Document the split-lock detection feature and its parameters.
