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). -----BEGIN PGP SIGNATURE----- iQJGBAABCAAwFiEE4fcc61cGeeHD/fCwgsRv/nhiVHEFAmWb8o8SHHJqd0Byand5 c29ja2kubmV0AAoJEILEb/54YlRxbOQP/2D+YGyd9R1awYqxQoIQSGbpIr7a9oTR BOIcOn2PvWLXH8w9wVbIUJsSL9Nx90D9T4S5QcyHrS2qHmR+1Gb0gX3D4QAmEBcG +wFCLt2//5PwqShtPcJEUcGdL274aVEpmnEAmzKnk20MkLQM3twxe6FKSkwWMLYb u9OKgdN8Vah0iSBUCpyT52O0x4d65MD/tka0QaGjLg64TtyqhTSKi+XgWtZkSZ7H lRgn9qMoMXq/h1aeK4MKp5UtJKRxBWRdMijIFFXAfgO8dwbDbyXTo0d2LMR6DiEM VsvRIjEePoRcGf7bwAbrUeSoNb5Ec32RW3v9GSNn2sWutW+vhD//frZq48zAR6lm i8Xlf2Ar63Z+qNcFpCZjlNwAbfEuZ1vIr0Pu3oDd0GkOXjxiVMgAwtatTp1nSW7/ wWFuMA5G+wdzU/Z5KcV1p7S8CP1gC8S05LHGwtKKGm9pLbzhauF8GK6Xpa4711T8 oI3uDFIgxaxW8B/ymsM5cNa2QbfYUuQbOFTwXvBcy4gizrbZwwXRSpfaKoDIYAXZ 2kfwmFbu3IbrRypboY58lG3SzbnN94oEMANtsVYuxMimGz2x3ZmHBAFm2l9YPYRz dBq/RUM7sMIvM1SwqR4tG8rt206L7KpPyW99pUa2AhEdof4iV2bpyujHFdkm83MK nJ0OF/xcc98Z =zh4c -----END PGP SIGNATURE----- Merge tag 'pm-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm 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.
