Merge tag 'pm+acpi-3.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull more ACPI and power management updates from Rafael Wysocki: "These are a couple of regression fixes, cpuidle menu governor optimizations, fixes for ACPI proccessor and battery drivers, hibernation fix to avoid problems related to the e820 memory map, fixes for a few cpufreq drivers and a new version of the suspend profiling tool analyze_suspend.py. Specifics: - Fix for an ACPI-based device hotplug regression introduced in 3.14 that causes a kernel panic to trigger when memory hot-remove is attempted with CONFIG_ACPI_HOTPLUG_MEMORY unset from Tang Chen - Fix for a cpufreq regression introduced in 3.16 that triggers a "sleeping function called from invalid context" bug in dev_pm_opp_init_cpufreq_table() from Stephen Boyd - ACPI battery driver fix for a warning message added in 3.16 that prints silly stuff sometimes from Mariusz Ceier - Hibernation fix for safer handling of mismatches in the 820 memory map between the configurations during image creation and during the subsequent restore from Chun-Yi Lee - ACPI processor driver fix to handle CPU hotplug notifications correctly during system suspend/resume from Lan Tianyu - Series of four cpuidle menu governor cleanups that also should speed it up a bit from Mel Gorman - Fixes for the speedstep-smi, integrator, cpu0 and arm_big_little cpufreq drivers from Hans Wennborg, Himangi Saraogi, Markus Pargmann and Uwe Kleine-König - Version 3.0 of the analyze_suspend.py suspend profiling tool from Todd E Brandt" * tag 'pm+acpi-3.17-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / battery: Fix warning message in acpi_battery_get_state() PM / tools: analyze_suspend.py: update to v3.0 cpufreq: arm_big_little: fix module license spec cpufreq: speedstep-smi: fix decimal printf specifiers ACPI / hotplug: Check scan handlers in acpi_scan_hot_remove() cpufreq: OPP: Avoid sleeping while atomic cpufreq: cpu0: Do not print error message when deferring cpufreq: integrator: Use set_cpus_allowed_ptr PM / hibernate: avoid unsafe pages in e820 reserved regions ACPI / processor: Make acpi_cpu_soft_notify() process CPU FROZEN events cpuidle: menu: Lookup CPU runqueues less cpuidle: menu: Call nr_iowait_cpu less times cpuidle: menu: Use ktime_to_us instead of reinventing the wheel cpuidle: menu: Use shifts when calculating averages where possible
