Merge tag 'pm-4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management fixes from Rafael Wysocki:
 "This includes a stable-candidate cpufreq-dt driver problem fix and
  annotations of tracepoints in the runtime PM framework.

  Specifics:

   - Fix the definition of the cpufreq-dt driver's machines table
     introduced during the 4.7 cycle that should be NULL-terminated, but
     the termination entry is missing from it (Wei Yongjun).

   - Annotate tracepoints in the runtime PM framework's core so as to
     allow the functions containing them to be called from the idle code
     path without causing RCU to complain about illegal usage (Paul
     McKenney)"

* tag 'pm-4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  PM / runtime: Add _rcuidle suffix to allow rpm_idle() use from idle
  PM / runtime: Add _rcuidle suffix to allow rpm_resume() to be called from idle
  cpufreq: dt: Add terminate entry for of_device_id tables
