Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.18-rc1

with top-most commit ec3d8b8365e9865b43099e943ec5f0bc12f28f96

 Merge branch 'pm-tools'

on top of commit 7e57714cd0ad2d5bb90e50b5096a0e671dec1ef3

 Linux 5.17-rc6

to receive power management updates for 5.18-rc1.

These are mostly fixes and cleanups all over the code and a new
piece of documentation for Intel uncore frequency scaling.

Functionality-wise, the intel_idle driver will support Sapphire
Rapids Xeons natively now (with some extra facilities for controlling
C-states more precisely on those systems), virtual guests will take
the ACPI S4 hardware signature into account by default, the
intel_pstate driver will take the defualt EPP value from the
firmware, cpupower utility will support the AMD P-state driver added
in the previous cycle and there is a new tracer utility for that
driver.

Specifics:

 - Allow device_pm_check_callbacks() to be called from interrupt
   context without issues (Dmitry Baryshkov).

 - Modify devm_pm_runtime_enable() to automatically handle
   pm_runtime_dont_use_autosuspend() at driver exit time (Douglas
   Anderson).

 - Make the schedutil cpufreq governor use to_gov_attr_set() instead
   of open coding it (Kevin Hao).

 - Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the
   cpufreq longhaul driver (Rafael Wysocki).

 - Unify show() and store() naming in cpufreq and make it use
   __ATTR_XX (Lianjie Zhang).

 - Make the intel_pstate driver use the EPP value set by the firmware
   by default (Srinivas Pandruvada).

 - Re-order the init checks in the powernow-k8 cpufreq driver (Mario
   Limonciello).

 - Make the ACPI processor idle driver check for architectural
   support for LPI to avoid using it on x86 by mistake (Mario
   Limonciello).

 - Add Sapphire Rapids Xeon support to the intel_idle driver (Artem
   Bityutskiy).

 - Add 'preferred_cstates' module argument to the intel_idle driver
   to work around C1 and C1E handling issue on Sapphire Rapids (Artem
   Bityutskiy).

 - Add core C6 optimization on Sapphire Rapids to the intel_idle
   driver (Artem Bityutskiy).

 - Optimize the haltpoll cpuidle driver a bit (Li RongQing).

 - Remove leftover text from intel_idle() kerneldoc comment and fix
   up white space in intel_idle (Rafael Wysocki).

 - Fix load_image_and_restore() error path (Ye Bin).

 - Fix typos in comments in the system wakeup hadling code (Tom Rix).

 - Clean up non-kernel-doc comments in hibernation code (Jiapeng
   Chong).

 - Fix __setup handler error handling in system-wide suspend and
   hibernation core code (Randy Dunlap).

 - Add device name to suspend_report_result() (Youngjin Jang).

 - Make virtual guests honour ACPI S4 hardware signature by
   default (David Woodhouse).

 - Block power off of a parent PM domain unless child is in deepest
   state (Ulf Hansson).

 - Use dev_err_probe() to simplify error handling for generic PM
   domains (Ahmad Fatoum).

 - Fix sleep-in-atomic bug caused by genpd_debug_remove() (Shawn Guo).

 - Document Intel uncore frequency scaling (Srinivas Pandruvada).

 - Add DTPM hierarchy description (Daniel Lezcano).

 - Change the locking scheme in DTPM (Daniel Lezcano).

 - Fix dtpm_cpu cleanup at exit time and missing virtual DTPM pointer
   release (Daniel Lezcano).

 - Make dtpm_node_callback[] static (kernel test robot).

 - Fix spelling mistake "initialze" -> "initialize" in
   dtpm_create_hierarchy() (Colin Ian King).

 - Add tracer tool for the amd-pstate driver (Jinzhou Su).

 - Fix PC6 displaying in turbostat on some systems (Artem Bityutskiy).

 - Add AMD P-State support to the cpupower utility (Huang Rui).

Thanks!
