Specifics: 1) After the recent locking changes in the cpufreq core it is possible to trigger BUG_ON(!policy) in lock_policy_rwsem_read() if cpufreq_get() is called before registering a cpufreq driver. Fix from Viresh Kumar. 2) If intel_pstate has been loaded already, it doesn't make sense to do anything in acpi_cpufreq_init() and moreover doing something in there in that case may be harmful, so make that function return immediately if another cpufreq driver is already present. From Yinghai Lu. 3) The ACPI IPMI driver sometimes attempts to acquire a mutex from interrupt context, which can be avoided by replacing that mutex with a spinlock. From Lv Zheng. 4) A NULL pointer may be dereferenced by the exynos5440 cpufreq driver if a memory allocation made by it fails. Fix from Sachin Kamat. 5) Hanjun Guo's commit fixes a typo in the kerneldoc comment documenting acpi_bus_unregister_driver()" * tag 'pm+acpi-3.12-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: ACPI / scan: fix typo in comments of acpi_bus_unregister_driver() cpufreq: exynos5440: Fix potential NULL pointer dereference cpufreq: check cpufreq driver is valid and cpufreq isn't disabled in cpufreq_get() acpi-cpufreq: skip loading acpi_cpufreq after intel_pstate ACPI / IPMI: Fix atomic context requirement of ipmi_msg_handler() --- ec220be785cc782ff7e77f79e4b6b749570739bf
