Merge tag 'pm+acpi-3.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI and power management updates from Rafael Wysocki: "This is material that didn't make it to my 3.18-rc1 pull request for various reasons, mostly related to timing and travel (LinuxCon EU / LPC) plus a couple of fixes for recent bugs. The only really new thing here is the PM QoS class for memory bandwidth, but it is simple enough and users of it will be added in the next cycle. One major change in behavior is that platform devices enumerated by ACPI will use 32-bit DMA mask by default. Also included is an ACPICA update to a new upstream release, but that's mostly cleanups, changes in tools and similar. The rest is fixes and cleanups mostly. Specifics: - Fix for a recent PCI power management change that overlooked the fact that some IRQ chips might not be able to configure PCIe PME for system wakeup from Lucas Stach. - Fix for a bug introduced in 3.17 where acpi_device_wakeup() is called with a wrong ordering of arguments from Zhang Rui. - A bunch of intel_pstate driver fixes (all -stable candidates) from Dirk Brandewie, Gabriele Mazzotta and Pali Rohár. - Fixes for a rather long-standing problem with the OOM killer and the freezer that frozen processes killed by the OOM do not actually release any memory until they are thawed, so OOM-killing them is rather pointless, with a couple of cleanups on top (Michal Hocko, Cong Wang, Rafael J Wysocki). - ACPICA update to upstream release 20140926, inlcuding mostly cleanups reducing differences between the upstream ACPICA and the kernel code, tools changes (acpidump, acpiexec) and support for the _DDN object (Bob Moore, Lv Zheng). - New PM QoS class for memory bandwidth from Tomeu Vizoso. - Default 32-bit DMA mask for platform devices enumerated by ACPI (this change is mostly needed for some drivers development in progress targeted at 3.19) from Heikki Krogerus. - ACPI EC driver cleanups, mostly related to debugging, from Lv Zheng. - cpufreq-dt driver updates from Thomas Petazzoni. - powernv cpuidle driver update from Preeti U Murthy" * tag 'pm+acpi-3.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (34 commits) intel_pstate: Correct BYT VID values. intel_pstate: Fix BYT frequency reporting intel_pstate: Don't lose sysfs settings during cpu offline cpufreq: intel_pstate: Reflect current no_turbo state correctly cpufreq: expose scaling_cur_freq sysfs file for set_policy() drivers cpufreq: intel_pstate: Fix setting max_perf_pct in performance policy PCI / PM: handle failure to enable wakeup on PCIe PME ACPI: invoke acpi_device_wakeup() with correct parameters PM / freezer: Clean up code after recent fixes PM: convert do_each_thread to for_each_process_thread OOM, PM: OOM killed task shouldn't escape PM suspend freezer: remove obsolete comments in __thaw_task() freezer: Do not freeze tasks killed by OOM killer ACPI / platform: provide default DMA mask cpuidle: powernv: Populate cpuidle state details by querying the device-tree cpufreq: cpufreq-dt: adjust message related to regulators cpufreq: cpufreq-dt: extend with platform_data cpufreq: allow driver-specific data ACPI / EC: Cleanup coding style.
