Merge tag 'pm-4.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki: "More hibernation-related material: one fix for a recent regression in the core, one small cleanup of the x86-64 resume code and a documentation update. Specifics: - Fix a hibernate core regression resulting from uncovering a latent bug in its implementation of memory bitmaps by a recent commit (James Morse). - Use __pa() to compute a physical address in the x86-64 code finalizing resume from hibernation (Rafael Wysocki). - Update power management documentation related to system sleep states to remove outdated information from it and to add a description of a recently introduced hibernation debug feature to it (Rafael Wysocki)" * tag 'pm-4.8-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: PM / hibernate: Fix rtree_next_node() to avoid walking off list ends x86/power/64: Use __pa() for physical address computation PM / sleep: Update some system sleep documentation
