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)" * tag 'pm-extra-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / sleep: Ignore spurious SCI wakeups from suspend-to-idle PM / wakeup: Integrate mechanism to abort transitions in progress x86/intel_idle: add Gemini Lake support cpuidle: check dev before usage in cpuidle_use_deepest_state() powercap: intel_rapl: Add support for Gemini Lake PM / Domains: Add DT file to MAINTAINERS PM / Domains: Fix DT example
