Subject: [PATCH 1/3] rt-tests: cyclictest: Remove histogram totals
The Total: line does not seem to contribute much value, as it should just
be the number of cycles minus the number of overflows. Unless someone
complains, remove it to simplify moving to common histogram code.

- Tested in rteval
- Edited commit message to say "cycles" instead of buckets
