* pm-tools:
  Creating a common structure initialization pattern for struct option
  cpupower: Enable disabled Cstates if they are below max latency
  cpupower: Remove debug message when using cpupower idle-set -D switch
  cpupower: cpupower monitor reports uninitialized values for offline cpus
  tools/power turbostat: bugfix: print MAX_NON_TURBO_RATIO
  tools/power turbostat: simplify Bzy_MHz calculation
