Merge tag 'pm-extra-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more power management updates from Rafael Wysocki:
 "These add new CPU IDs to a couple of drivers, fix a possible NULL
  pointer dereference in the cpuidle core, update DT-related things in
  the generic power domains framework and finally update the
  suspend/resume infrastructure to improve the handling of wakeups from
  suspend-to-idle.

  Specifics:

   - Add Intel Gemini Lake CPU IDs to the intel_idle and intel_rapl
     drivers (David Box).

   - Add a NULL pointer check to the cpuidle core to prevent it from
     crashing on platforms with incomplete cpuidle configuration (Fei
     Li).

   - Fix DT-related documentation in the generic power domains (genpd)
     framework and add a MAINTAINERS entry for DT-related material in
     genpd (Viresh Kumar).

   - Update the system suspend/resume infrastructure to improve the
     handling of aborts of suspend transitions in progress in the wakeup
     framework and rework the suspend-to-idle core loop to make it
     possible to filter out spurious wakeup events (specifically the
     ones coming from ACPI) without resuming all the way up to user
     space every time (Rafael Wysocki)"
