Merge branches 'pm-core', 'pm-runtime' and 'pm-sleep'

Merge changes related to system sleep and runtime PM framework for
6.18-rc1:

 - Annotate loops walking device links in the power management core
   code as _srcu and add macros for walking device links to reduce the
   likelihood of coding mistakes related to them (Rafael Wysocki)

 - Document time units for *_time functions in the runtime PM API (Brian
   Norris)

 - Clear power.must_resume in noirq suspend error path to avoid resuming
   a dependant device under a suspended parent or supplier (Rafael
   Wysocki)

 - Fix GFP mask handling during hybrid suspend and make the amdgpu
   driver handle hybrid suspend correctly (Mario Limonciello, Rafael
   Wysocki)

 - Fix GFP mask handling after aborted hibernation in platform mode and
   combine exit paths in power_down() to avoid code duplication (Rafael
   Wysocki)

 - Use vmalloc_array() and vcalloc() in the hibernation core to avoid
   open-coded size computations (Qianfeng Rong)

 - Fix typo in hibernation core code comment (Li Jun)

 - Call pm_wakeup_clear() in the same place where other functions that do
   bookkeeping prior to suspend_prepare() are called (Samuel Wu)
