Merge branches 'pm-sleep', 'pm-powercap' and 'pm-tools'refs/merge-window/b7b9fef85ccd38cebf187688b321fb1bd2429d63

Merge updates related to system sleep support, two updates of the
intel_rapl power capping driver, and a pm-graph utility fix for
7.2-rc1:

 - Add sysctl interface for DPM watchdog timeouts (Tzung-Bi Shih)

 - Use complete() instead of complete_all() in device_pm_sleep_init() to
   avoid a false-positive warning from lockdep_assert_RT_in_threaded_ctx()
   when CONFIG_PROVE_RAW_LOCK_NESTING is enabled (Jiakai Xu)

 - Use a flexible array for CRC uncompressed buffers during hibernation
   image saving (Rosen Penev)

 - Make the LZ4 algorithm available for hibernation compression (l1rox3)

 - Move the preallocate_image() call during hibernation after the
   "prepare" phase of the "freeze" transition (Matthew Leach)

 - Fix a memory leak in rapl_add_package_cpuslocked() in the intel_rapl
   power capping driver and use sysfs_emit() in cpumask_show() in that
   driver (Sumeet Pawnikar, Yury Norov)

 - Fix ValueError when parsing incomplete device properties in the
   pm-graph utility (Gongwei Li)
