- * The rule for padding:
- * Best is power of two because then the right structure can be found by a
- * simple shift. The structure should be always cache line aligned.
- * gcc needs n=alignto(cachelinesize, popcnt(sizeof(bla_mib))) shift/add
- * instructions to emulate multiply in case it is not power-of-two.
- * Currently n is always <=3 for all sizes so simple cache line alignment
- * is enough.

- * The best solution would be a global CPU local area , especially on 64
- * and 128byte cacheline machine it makes a *lot* of sense -AK
