nohz: Fix update_ts_time_stat idle accounting

2011-09-08T09:10:55Z

update_ts_time_stat currently updates idle time even if we are in iowait loop at the moment. The only real users of the idle counter (via get_cpu_idle_time_us) are CPU governors and they expect to get cumulative time for both idle and iowait times. The value (idle_sleeptime) is also printed to userspace by print_cpu but it prints both idle and iowait times so the idle part is misleading. Let's clean this up and fix update_ts_time_stat to account both counters properly and update consumers of idle to consider iowait time as well. If we do this we might use get_cpu_{idle,iowait}_time_us from other contexts as well and we will get expected values.

[CPUFREQ] Remove unneeded locks

2011-03-16T21:54:32Z

There cannot be any concurrent access to these through different cpu sysfs files anymore, because these tunables are now all global (not per cpu). I still have some doubts whether some of these locks were needed at all. Anyway, let's get rid of them. Signed-off-by: Thomas Renninger Signed-off-by: Dave Jones CC: cpufreq@vger.kernel.org

cpufreq: use system_wq instead of dedicated workqueues

2011-01-26T11:12:50Z

With cmwq, there's no reason for cpufreq drivers to use separate workqueues. Remove the dedicated workqueues from cpufreq_conservative and cpufreq_ondemand and use system_wq instead. The work items are already sync canceled on stop, so it's already guaranteed that no work is running on module exit. Signed-off-by: Tejun Heo Acked-by: Dave Jones Cc: cpufreq@vger.kernel.org

cpufreq: Unify sysfs attribute definition macros

Multiple modules used to define those which are with identical functionality and were needlessly replicated among the different cpufreq drivers. Push them into the header and remove duplication.
