Hi,
This is rather extreme, but I think that we should make the scheduler paths as lightweight as reasonably possible.
[1/2] removes the atomic work counter incrementation from gov_cancel_work() as it is not necessary any more.
[2/2] changes the way work items are handled by dbs_update_util_handler() and dbs_work_handler() to avoid extra atomic operations in cases when they aren't really necessary (policy objects serving one CPU only).
On top of the pm-cpufreq-test branch of linux-pm.git. Lightly tested, but I don't have systems where policy objects are shared.
Thanks, Rafael
