Merge tag 'pm+acpi-for-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI and power management updates from Rafael Wysocki: - Introduction of device PM QoS flags. - ACPI device power management update allowing subsystems other than PCI to use it more easily. - ACPI device enumeration rework allowing additional kinds of devices to be enumerated via ACPI. From Mika Westerberg, Adrian Hunter, Mathias Nyman, Andy Shevchenko, and Rafael J. Wysocki. - ACPICA update to version 20121018 from Bob Moore and Lv Zheng. - ACPI memory hotplug update from Wen Congyang and Yasuaki Ishimatsu. - Introduction of acpi_handle_<level>() messaging macros and ACPI-based CPU hot-remove support from Toshi Kani. - ACPI EC updates from Feng Tang. - cpufreq updates from Viresh Kumar, Fabio Baltieri and others. - cpuidle changes to quickly notice governor prediction failure from Youquan Song. - Support for using multiple cpuidle drivers at the same time and cpuidle cleanups from Daniel Lezcano. - devfreq updates from Nishanth Menon and others. - cpupower update from Thomas Renninger. - Fixes and small cleanups all over the place. * tag 'pm+acpi-for-3.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (196 commits) mmc: sdhci-acpi: enable runtime-pm for device HID INT33C6 ACPI: add Haswell LPSS devices to acpi_platform_device_ids list ACPI: add documentation about ACPI 5 enumeration pnpacpi: fix incorrect TEST_ALPHA() test ACPI / PM: Fix header of acpi_dev_pm_detach() in acpi.h ACPI / video: ignore BIOS initial backlight value for HP Folio 13-2000 ACPI : do not use Lid and Sleep button for S5 wakeup ACPI / PNP: Do not crash due to stale pointer use during system resume ACPI / video: Add "Asus UL30VT" to ACPI video detect blacklist ACPI: do acpisleep dmi check when CONFIG_ACPI_SLEEP is set spi / ACPI: add ACPI enumeration support gpio / ACPI: add ACPI support PM / devfreq: remove compiler error with module governors (2) cpupower: IvyBridge (0x3a and 0x3e models) support cpupower: Provide -c param for cpupower monitor to schedule process on all cores cpupower tools: Fix warning and a bug with the cpu package count cpupower tools: Fix malloc of cpu_info structure cpupower tools: Fix issues with sysfs_topology_read_file cpupower tools: Fix minor warnings cpupower tools: Update .gitignore for files created in the debug directories ...
