That maybe so but this newly added loop which is only Calxeda-relevant is called in cpufreq_stat_notifier_trans, which is the frequency change notifier call, AFAICT. So each cpufreq driver will be paying that small and needless penalty now for nothing and on each frequency change. Which adds to the kernel-wide bloat and we absolutely don't want that. So you probably need to find a slick way of detecting calxeda hw somewhere along the init path of cpufreq_stats_init and set a hw-specific flag instead of adding that cost to each driver.
