Merge branches 'pm-sleep', 'powercap', 'pm-domains' and 'pm-cpufreq'

* pm-sleep:
  PM / sleep: Fix test_suspend= command line option

* powercap:
  powercap / RAPL: change domain detection message
  powercap / RAPL: add support for CPU model 0x3f

* pm-domains:
  PM / domains: Make generic_pm_domain.name const

* pm-cpufreq:
  cpufreq: intel_pstate: Remove unneeded variable
