Linus Torvalds 7da71072e1 Power management updates for 6.8-rc1
- Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs to
    the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui).
 
  - Do not enable interrupts when entering idle in the haltpoll cpuidle
    driver (Borislav Petkov).
 
  - Add Emerald Rapids support in no-HWP mode to the intel_pstate cpufreq
    driver (Zhenguo Yao).
 
  - Use EPP values programmed by the platform firmware as balanced
    performance ones by default in intel_pstate (Srinivas Pandruvada).
 
  - Add a missing function return value check to the SCMI cpufreq driver
    to avoid unexpected behavior (Alexandra Diupina).
 
  - Fix parameter type warning in the armada-8k cpufreq driver (Gregory
    CLEMENT).
 
  - Rework trans_stat_show() in the devfreq core code to avoid buffer
    overflows (Christian Marangi).
 
  - Synchronize devfreq_monitor_[start/stop] so as to prevent a timer
    list corruption from occurring when devfreq governors are switched
    frequently (Mukesh Ojha).
 
  - Fix possible deadlocks in the core system-wide PM code that occur if
    device-handling functions cannot be executed asynchronously during
    resume from system-wide suspend (Rafael J. Wysocki).
 
  - Clean up unnecessary local variable initializations in multiple
    places in the hibernation code (Wang chaodong, Li zeming).
 
  - Adjust core hibernation code to avoid missing wakeup events that
    occur after saving an image to persistent storage (Chris Feng).
 
  - Update hibernation code to enforce correct ordering during image
    compression and decompression (Hongchen Zhang).
 
  - Use kmap_local_page() instead of kmap_atomic() in copy_data_page()
    during hibernation and restore (Chen Haonan).
 
  - Adjust documentation and code comments to reflect recent tasks freezer
    changes (Kevin Hao).
 
  - Repair excess function parameter description warning in the
    hibernation image-saving code (Randy Dunlap).
 
  - Fix _set_required_opps when opp is NULL (Bryan O'Donoghue).
 
  - Use device_get_match_data() in the OPP code for TI (Rob Herring).
 
  - Clean up OPP level and other parts and call dev_pm_opp_set_opp()
    recursively for required OPPs (Viresh Kumar).

Pull power management updates from Rafael Wysocki:
 "These add support for new processors (Sierra Forest, Grand Ridge and
  Meteor Lake) to the intel_idle driver, make intel_pstate run on
  Emerald Rapids without HWP support and adjust it to utilize EPP values
  supplied by the platform firmware, fix issues, clean up code and
  improve documentation.

  The most significant fix addresses deadlocks in the core system-wide
  resume code that occur if async_schedule_dev() attempts to run its
  argument function synchronously (for example, due to a memory
  allocation failure). It rearranges the code in question which may
  increase the system resume time in some cases, but this basically is a
  removal of a premature optimization. That optimization will be added
  back later, but properly this time.

  Specifics:

   - Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs
     to the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui)

   - Do not enable interrupts when entering idle in the haltpoll cpuidle
     driver (Borislav Petkov)

   - Add Emerald Rapids support in no-HWP mode to the intel_pstate
     cpufreq driver (Zhenguo Yao)

   - Use EPP values programmed by the platform firmware as balanced
     performance ones by default in intel_pstate (Srinivas Pandruvada)

   - Add a missing function return value check to the SCMI cpufreq
     driver to avoid unexpected behavior (Alexandra Diupina)

   - Fix parameter type warning in the armada-8k cpufreq driver (Gregory
     CLEMENT)

   - Rework trans_stat_show() in the devfreq core code to avoid buffer
     overflows (Christian Marangi)

   - Synchronize devfreq_monitor_[start/stop] so as to prevent a timer
     list corruption from occurring when devfreq governors are switched
     frequently (Mukesh Ojha)

   - Fix possible deadlocks in the core system-wide PM code that occur
     if device-handling functions cannot be executed asynchronously
     during resume from system-wide suspend (Rafael J. Wysocki)

   - Clean up unnecessary local variable initializations in multiple
     places in the hibernation code (Wang chaodong, Li zeming)

   - Adjust core hibernation code to avoid missing wakeup events that
     occur after saving an image to persistent storage (Chris Feng)

   - Update hibernation code to enforce correct ordering during image
     compression and decompression (Hongchen Zhang)

   - Use kmap_local_page() instead of kmap_atomic() in copy_data_page()
     during hibernation and restore (Chen Haonan)

   - Adjust documentation and code comments to reflect recent tasks
     freezer changes (Kevin Hao)

   - Repair excess function parameter description warning in the
     hibernation image-saving code (Randy Dunlap)

   - Fix _set_required_opps when opp is NULL (Bryan O'Donoghue)
