intel_pstate: Remove periodic P state boost
Remove the periodic P state boost. This code required for some corner case benchmark tests. The calculation of the required P state was incorrect/inaccurate and would not allow P state increase. This was fixed by a combination of commits: 2134ed4 cpufreq / intel_pstate: Change to scale off of max P-state d253d2a intel_pstate: Improve accuracy by not truncating until final result References: https://bugzilla.kernel.org/show_bug.cgi?id=64271 Reported-by: Doug Smythies <dsmythies@telus.net> Signed-off-by: Dirk Brandewie <dirk.j.brandewie@intel.com> Signed-off-by: Rafael J.
