This patch series introduces support for CPU overclocking technique called Boost. It is a follow up of a LAB governor proposal. Boost is a LAB component: http://thread.gmane.org/gmane.linux.kernel/1484746/match=cpufreq Boost unifies hardware based solution (e.g. Intel Nehalem) with software oriented one (like the one done at Exynos). For this reason cpufreq/freq_table code has been reorganized to include common code. Important design decisions: - Boost related code is compiled-in unconditionally and disabled by default The cpufreq_driver is responsibile for providing set_boost_freq callback (if needed) - struct cpufreq_driver has been extended with boost related fields: -- boost_supported - when driver supports boosting -- set_boost_freq - callback to function, which is necessary to enable boost at the processor (like it is done at Intel) - Boost sysfs attributies are seen only when cpufreq driver supports them. They will not show up until either cpufreq_driver defines boost_supported flag or device tree's cpufreq "boost_mode" attribute. - No special spin_lock for Boost was created. The one from cpufreq_driver was reused. - The Boost code doesn't rely on any policy. When boost state is changed, then policies attached to each CPU are updated.
