From: Rafael J. Wysocki <rafael.j.wyso...@intel.com>
Add a new field to be set when the CPUFREQ_GOV_FLAG_STRICT_TARGET
flag is set for the current governor to struct cpufreq_policy, so
that the drivers needing to check CPUFREQ_GOV_FLAG_STRICT_TARGET do
not have to access the governor object during every frequency
transition.
