cpufreq / intel_pstate: Change to scale off of max P-state
Change to using max P-state instead of max turbo P-state. This change resolves two issues. On a quiet system intel_pstate can fail to respond to a load change. On CPU SKUs that have a limited number of P-states and no turbo range intel_pstate fails to select the highest available P-state. This change is suitable for stable v3.9+ References: https://bugzilla.kernel.org/show_bug.cgi?id=59481 Reported-and-tested-by: Arjan van de Ven <arjan@linux.intel.com> Reported-and-tested-by: dsmythies@telus.net Signed-off-by: Dirk Brandewie <dirk.j.brandewie@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Cc: 3.9+ <stable@vger.kernel.org> Signed-off-by: Rafael J.
