ACPI and power management fixes for 3.12-rc3 1) After 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(). /

ACPI and power management fixes for 3.12-rc2 1) Four fixes for cpufreq regressions introduced by the changes that removed Device Tree parsing for CPU device nodes from cpufreq drivers from Sudeep KarkadaNagesha. 2) Two fixes for recent cpufreq regressions introduced by changes related to the preservation of sysfs attributes over system suspend/resume cycles from Viresh Kumar. 3) Fix for ACPI-based wakeup signaling in the PCI subsystem that fails to stop PME polling for devices put into the D3cold power state from Rafael J Wysocki. 4) Fix for bad interactions between cpufreq and udev on systems supporting intel_pstate where acpi-cpufreq is available as well from Yinghai Lu. /

kvm-3.12-1
The highlights of the release are nested EPT and pv-ticketlocks support (hypervisor part; guest part, which is most of the code, goes through tip tree). Apart of that there are many fixes for all arches.

IOMMU Updates for Linux v3.12 This round the updates contain: * A new driver for the Freescale PAMU IOMMU from Varun Sethi. This driver has cooked for a while and required changes to the IOMMU-API and infrastructure that were already merged before. * Updates for the ARM-SMMU driver from Will Deacon * Various fixes, the most important one is probably a fix from Alex Williamson for a memory leak in the VT-d page-table freeing code In summary not all that much. The biggest part in the diffstat is the new PAMU driver.
