Hey Viresh,
Thanks for taking time to review the series.

In the existing code, per-policy flags doesn't have any impact i.e.
if cpufreq_driver boost is enabled and one or more of the per-policy
boost is disabled, the cpufreq driver will behave as if boost is
enabled. I had to update the policy->boost_enabled value because we seem
to allow enabling cpufreq_driver.boost_enabled from the driver, but I
can drop that because it was just for book keeping. I didn't want
to include redundant info from another mail thread that I referenced in
the cover letter, but will add more info in the re-spin.
