- Fix two cpufreq regressions causing undesirable changes in behavior to appear (one in the core and one in the conservative governor) introduced during the 4.8 cycle (Aaro Koskinen, Rafael Wysocki). - Fix the way the intel_pstate driver accesses MSRs related to the hardware-managed P-states (HWP) feature during the initialization which currently is unsafe and may cause the processor to generate a general protection fault (Srinivas Pandruvada). - Rework the intel_pstate's P-state selection algorithm used on Atom processors to avoid known problems with the current one and to make the computation more straightforward, which also happens to improve performance in multiple benchmarks a bit (Rafael Wysocki). - Improve two comments in the intel_pstate driver (Rafael Wysocki). - Fix the desired performance computation in the CPPC cpufreq driver (Hoan Tran). - Fix the devfreq core to avoid printing misleading error messages in some cases (Tobias Jakobi). - Fix the error code path in devfreq_add_device() to use proper locking around list modifications (Axel Lin). - Fix a build failure and remove a couple of redundant updates of variables in the exynos-nocp devfreq driver (Axel Lin). -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABCAAGBQJYANqMAAoJEILEb/54YlRx+U4P/A1ZJ/93u+ChipehTckNDogR xMCNsUz6Pn9VIdilEnaUcsCaNc93R7e6KjwgSO7Caeriw4syW3YZz2LuGQTihs8b 5vnvVvya9Bw1aXUweeayogMyOYZV1y1G/yzq7/+c02/cgxO8WBPnmGrE17Mhu43q IF1pQJ257e0HgKKspuzy+twRCLwnOqHbvWtQnEi2rzuaGrsK7XZk9yRuaXK4NshQ +M9hrHlw+OdmI+9lLmH8Ap2G68EJ4Q2o69sbAQ6MWgxRU44D0uEqgbT16cIdDs3J c9VCgiqHuhj2bfd9vqNAjr4bGdy4iwcEKyz2nkIl0KEq9tTPtJky8v6WUzV0+rbR xVbGIWg8X5wKe/Ndve2GLDrqhuVJ0hZkRdqpzRgm08VBGpRlmM0Gjqk+uEKqA2n2 IhidwTlzbQFVh437cjqupCKVXPb2POdgNyk4fEK7WVckRR3K7LR+rXoWN1uwW2YJ 9rjQBX0n2UfZ9Ft+gVO6/faWZlqLPmx60lHQSXNHvNY04HfZ5EiRFGEZEX1g0Uep 16nYHpB+qx/GwR7druGQVVY58YEp2g68jbpL2ehr2lLBYVSExy0kiOrS7GpoA0vd ngImjroJ842wQYjfek4Gi8VfGu+tsuMIVdjltOn1sVZ1QvprgF/atZHcN84eV8BU OyEGOQ7H1idEZ14Oa19C =3yoB -----END PGP SIGNATURE----- Merge tag 'pm-extra-4.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more power management updates from Rafael Wysocki: "This includes a couple of fixes for cpufreq regressions introduced in 4.8, a rework of the intel_pstate algorithm used on Atom processors (that took some time to test) plus a fix and a couple of cleanups in that driver, a CPPC cpufreq driver fix, and a some devfreq fixes and cleanups (core and exynos-nocp).
