Merge tag 'pm-4.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki: "Two hibernation fixes allowing it to work with the recently added randomization of the kernel identity mapping base on x86-64 and one cpufreq driver regression fix. Specifics: - Fix the x86 identity mapping creation helpers to avoid the assumption that the base address of the mapping will always be aligned at the PGD level, as it may be aligned at the PUD level if address space randomization is enabled (Rafael Wysocki). - Fix the hibernation core to avoid executing tracing functions before restoring the processor state completely during resume (Thomas Garnier). - Fix a recently introduced regression in the powernv cpufreq driver that causes it to crash due to an out-of-bounds array access (Akshay Adiga)" * tag 'pm-4.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / hibernate: Restore processor state before using per-CPU variables x86/power/64: Always create temporary identity mapping correctly cpufreq: powernv: Fix crash in gpstate_timer_handler()
