Power management and ACPI updates for 3.11-rc1 - Hotplug changes allowing device hot-removal operations to fail gracefully (instead of crashing the kernel) if they cannot be carried out completely. From Rafael J Wysocki and Toshi Kani. - Freezer update from Colin Cross and Mandeep Singh Baines targeted at making the freezing of tasks a bit less heavy weight operation. - cpufreq resume fix from Srivatsa S Bhat for a regression introduced during the 3.10 cycle causing some cpufreq sysfs attributes to return wrong values to user space after resume. - New freqdomain_cpus sysfs attribute for the acpi-cpufreq driver to provide information previously available via related_cpus from Lan Tianyu. - cpufreq fixes and cleanups from Viresh Kumar, Jacob Shin, Heiko Stübner, Xiaoguang Chen, Ezequiel Garcia, Arnd Bergmann, and Tang Yuantian. - Fix for an ACPICA regression causing suspend/resume issues to appear on some systems introduced during the 3.4 development cycle from Lv Zheng. - ACPICA fixes and cleanups from Bob Moore, Tomasz Nowicki, Lv Zheng, Chao Guan, and Zhang Rui. - New cupidle driver for Xilinx Zynq processors from Michal Simek. - cpuidle fixes and cleanups from Daniel Lezcano. - Changes to make suspend/resume work correctly in Xen guests from Konrad Rzeszutek Wilk. - ACPI device power management fixes and cleanups from Fengguang Wu and Rafael J Wysocki. - ACPI documentation updates from Lv Zheng, Aaron Lu and Hanjun Guo. - Fix for the IA-64 issue that was the reason for reverting commit 9f29ab1 and updates of the ACPI scan code from Rafael J Wysocki. - Mechanism for adding CMOS RTC address space handlers from Lan Tianyu (to allow some EC-related breakage to be fixed on some systems). - Spec-compliant implementation of acpi_os_get_timer() from Mika Westerberg. - Modification of do_acpi_find_child() to execute _STA in order to to avoid situations in which a pointer to a disabled device object is returned instead of an enabled one with the same _ADR value. From Jeff Wu. - Intel BayTrail PCH (Platform Controller Hub) support for the ACPI Intel Low-Power Subsystems (LPSS) driver and modificaions of that driver to work around a couple of known BIOS issues from Mika Westerberg and Heikki Krogerus. - EC driver fix from Vasiliy Kulikov to make it use get_user() and put_user() instead of dereferencing user space pointers blindly. - Assorted ACPI code cleanups from Bjorn Helgaas, Nicholas Mazzuca and Toshi Kani. - Modification of the "runtime idle" helper routine to take the return values of the callbacks executed by it into account and to call rpm_suspend() if they return 0, which allows some code bloat reduction to be done, from Rafael J Wysocki and Alan Stern. - New trace points for PM QoS from Sahara <keun-o.park@windriver.com>. - PM QoS documentation update from Lan Tianyu. - Assorted core PM code cleanups and changes from Bernie Thompson, Bjorn Helgaas, Julius Werner, and Shuah Khan. - New devfreq driver for the Exynos5-bus device from Abhilash Kesavan. - Minor devfreq cleanups, fixes and MAINTAINERS update from MyungJoo Ham, Abhilash Kesavan, Paul Bolle, Rajagopal Venkat, and Wei Yongjun. - OMAP Adaptive Voltage Scaling (AVS) SmartReflex voltage control driver updates from Andrii Tseglytskyi and Nishanth Menon. /
