      Pull ACPI updates from Rafael Wysocki:
       "The new feaures here are the support for ACPI overlays (allowing ACPI
        tables to be loaded at any time from EFI variables or via configfs)
        and the LPI (Low-Power Idle) support.  Also notable is the ACPI-based
        NUMA support for ARM64.
        Apart from that we have two new drivers, for the DPTF (Dynamic Power
        and Thermal Framework) power participant device and for the Intel
        Broxton WhiskeyCove PMIC, some more PMIC-related changes, support for
        the Boot Error Record Table (BERT) in APEI and support for
        platform-initiated graceful shutdown.
        Plus two new pieces of documentation and usual assorted fixes and
        cleanups in quite a few places.
         - Support for ACPI SSDT overlays allowing Secondary System
           Description Tables (SSDTs) to be loaded at any time from EFI
           variables or via configfs (Octavian Purdila, Mika Westerberg).
         - Support for the ACPI LPI (Low-Power Idle) feature introduced in
           ACPI 6.0 and allowing processor idle states to be represented in
           ACPI tables in a hierarchical way (with the help of Processor
           Container objects) and support for ACPI idle states management on
           ARM64, based on LPI (Sudeep Holla).
         - General improvements of ACPI support for NUMA and ARM64 support for
           ACPI-based NUMA (Hanjun Guo, David Daney, Robert Richter).
         - General improvements of the ACPI table upgrade mechanism and ARM64
           support for that feature (Aleksey Makarov, Jon Masters).
         - Support for the Boot Error Record Table (BERT) in APEI and
           improvements of kernel messages printed by the error injection code
           (Huang Ying, Borislav Petkov).
         - New driver for the Intel Broxton WhiskeyCove PMIC operation region
           and support for the REGS operation region on Broxton, PMIC code
           cleanups (Bin Gao, Felipe Balbi, Paul Gortmaker).
         - New driver for the power participant device which is part of the
           Dynamic Power and Thermal Framework (DPTF) and DPTF-related code
           reorganization (Srinivas Pandruvada).
         - Support for the platform-initiated graceful shutdown feature
           introduced in ACPI 6.1 (Prashanth Prakash).
         - ACPI button driver update related to lid input events generated
           automatically on initialization and system resume that have been
           problematic for some time (Lv Zheng).
         - ACPI EC driver cleanups (Lv Zheng).
         - Documentation of the ACPICA release automation process and the
           in-kernel ACPI AML debugger (Lv Zheng).
         - New blacklist entry and two fixes for the ACPI backlight driver
           (Alex Hung, Arvind Yadav, Ralf Gerbig).
         - Cleanups of the ACPI pci_slot driver (Joe Perches, Paul Gortmaker).
         - ACPI CPPC code changes to make it more robust against possible
           defects in ACPI tables and new symbol definitions for PCC (Hoan
         - System reboot code modification to execute the ACPI _PTS (Prepare
           To Sleep) method in addition to _TTS (Ocean He).
         - ACPICA-related change to carry out lock ordering checks in ACPICA
           if ACPICA debug is enabled in the kernel (Lv Zheng).
         - Assorted minor fixes and cleanups (Andy Shevchenko, Baoquan He,
           Bhaktipriya Shridhar, Paul Gortmaker, Rafael Wysocki)"

      Pull power management updates from Rafael  Wysocki:
       "Again, the majority of changes go into the cpufreq subsystem, but
        there are no big features this time.  The cpufreq changes that stand
        out somewhat are the governor interface rework and improvements
        related to the handling of frequency tables.  Apart from those, there
        are fixes and new device/CPU IDs in drivers, cleanups and an
        improvement of the new schedutil governor.
        Next, there are some changes in the hibernation core, including a fix
        for a nasty problem related to the MONITOR/MWAIT usage by CPU offline
        during resume from hibernation, a few core improvements related to
        memory management during resume, a couple of additional debug features
        and cleanups.
        Finally, we have some fixes and cleanups in the devfreq subsystem,
        generic power domains framework improvements related to system
        suspend/resume, support for some new chips in intel_idle and in the
        power capping RAPL driver, a new version of the AnalyzeSuspend utility
        and some assorted fixes and cleanups.
         - Rework the cpufreq governor interface to make it more
           straightforward and modify the conservative governor to avoid using
           transition notifications (Rafael Wysocki).
         - Rework the handling of frequency tables by the cpufreq core to make
           it more efficient (Viresh Kumar).
         - Modify the schedutil governor to reduce the number of wakeups it
           causes to occur in cases when the CPU frequency doesn't need to be
           changed (Steve Muckle, Viresh Kumar).
         - Fix some minor issues and clean up code in the cpufreq core and
           governors (Rafael Wysocki, Viresh Kumar).
         - Add Intel Broxton support to the intel_pstate driver (Srinivas
         - Fix problems related to the config TDP feature and to the validity
           of the MSR_HWP_INTERRUPT register in intel_pstate (Jan Kiszka,
           Srinivas Pandruvada).
         - Make intel_pstate update the cpu_frequency tracepoint even if the
           frequency doesn't change to avoid confusing powertop (Rafael
         - Clean up the usage of __init/__initdata in intel_pstate, mark some
           of its internal variables as __read_mostly and drop an unused
           structure element from it (Jisheng Zhang, Carsten Emde).
         - Clean up the usage of some duplicate MSR symbols in intel_pstate
           and turbostat (Srinivas Pandruvada).
         - Update/fix the powernv, s3c24xx and mvebu cpufreq drivers (Akshay
           Adiga, Viresh Kumar, Ben Dooks).
         - Fix a regression (introduced during the 4.5 cycle) in the
           pcc-cpufreq driver by reverting the problematic commit (Andreas
         - Add support for Intel Denverton to intel_idle, clean up Broxton
           support in it and make it explicitly non-modular (Jacob Pan, Jan
           Beulich, Paul Gortmaker).
         - Add support for Denverton and Ivy Bridge server to the Intel RAPL
           power capping driver and make it more careful about the handing of
           MSRs that may not be present (Jacob Pan, Xiaolong Wang).
         - Fix resume from hibernation on x86-64 by making the CPU offline
           during resume avoid using MONITOR/MWAIT in the "play dead" loop
           which may lead to an inadvertent "revival" of a "dead" CPU and a
           page fault leading to a kernel crash from it (Rafael Wysocki).
         - Make memory management during resume from hibernation more
           straightforward (Rafael Wysocki).
         - Add debug features that should help to detect problems related to
           hibernation and resume from it (Rafael Wysocki, Chen Yu).
         - Clean up hibernation core somewhat (Rafael Wysocki).
         - Prevent KASAN from instrumenting the hibernation core which leads
           to large numbers of false-positives from it (James Morse).
         - Prevent PM (hibernate and suspend) notifiers from being called
           during the cleanup phase if they have not been called during the
           corresponding preparation phase which is possible if one of the
           other notifiers returns an error at that time (Lianwei Wang).
         - Improve suspend-related debug printout in the tasks freezer and
           clean up suspend-related console handling (Roger Lu, Borislav
         - Update the AnalyzeSuspend script in the kernel sources to version
           4.2 (Todd Brandt).
         - Modify the generic power domains framework to make it handle system
           suspend/resume better (Ulf Hansson).
         - Make the runtime PM framework avoid resuming devices synchronously
           when user space changes the runtime PM settings for them and
           improve its error reporting (Rafael Wysocki, Linus Walleij).
         - Fix error paths in devfreq drivers (exynos, exynos-ppmu,
           exynos-bus) and in the core, make some devfreq code explicitly
           non-modular and change some of it into tristate (Bartlomiej
           Zolnierkiewicz, Peter Chen, Paul Gortmaker).
         - Add DT support to the generic PM clocks management code and make it
           export some more symbols (Jon Hunter, Paul Gortmaker).
         - Make the PCI PM core code slightly more robust against possible
           driver errors (Andy Shevchenko).
         - Make it possible to change DESTDIR and PREFIX in turbostat (Andy

      Pull block driver updates from Jens Axboe:
       "This branch also contains core changes.  I've come to the conclusion
        that from 4.9 and forward, I'll be doing just a single branch.  We
        often have dependencies between core and drivers, and it's hard to
        always split them up appropriately without pulling core into drivers
        when that happens.
        That said, this contains:
         - separate secure erase type for the core block layer, from
         - set of discard fixes, from Christoph.

      Pull documentation updates from Jonathan Corbet:
       "Some big changes this month, headlined by the addition of a new
        formatted documentation mechanism based on the Sphinx system.
        The objectives here are to make it easier to create better-integrated
        (and more attractive) documents while (eventually) dumping our
        one-of-a-kind, cobbled-together system for something that is widely
        used and maintained by others.  There's a fair amount of information
        what's being done, why, and how to use it in:
        Closer to home, Documentation/kernel-documentation.rst describes how
        it works.
        For now, the new system exists alongside the old one; you should soon
        see the GPU documentation converted over in the DRM pull and some
        significant media conversion work as well.  Once all the docs have
        been moved over and we're convinced that the rough edges (of which are
        are a few) have been smoothed over, the DocBook-based stuff should go
        Primary credit is to Jani Nikula for doing the heavy lifting to make
        this stuff actually work; there has also been notable effort from
        Markus Heiser, Daniel Vetter, and Mauro Carvalho Chehab.
        Expect a couple of conflicts on the new index.rst file over the course
        of the merge window; they are trivially resolvable.  That file may be
        a bit of a conflict magnet in the short term, but I don't expect that
        situation to last for any real length of time.
        Beyond that, of course, we have the usual collection of tweaks,
        updates, and typo fixes"

      Pull s390 updates from Martin Schwidefsky:
       "There are a couple of new things for s390 with this merge request:
         - a new scheduling domain "drawer" is added to reflect the unusual
           topology found on z13 machines.  Performance tests showed up to 8
           percent gain with the additional domain.
         - the new crc-32 checksum crypto module uses the vector-galois-field
           multiply and sum SIMD instruction to speed up crc-32 and crc-32c.
         - proper __ro_after_init support, this requires RO_AFTER_INIT_DATA in
           the generic vmlinux.lds linker script definitions.
         - kcov instrumentation support.  A prerequisite for that is the
           inline assembly basic block cleanup, which is the reason for the
           net/iucv/iucv.c change.
         - support for 2GB pages is added to the hugetlbfs backend.
        Then there are two removals:
         - the oprofile hardware sampling support is dead code and is removed.
           The oprofile user space uses the perf interface nowadays.
         - the ETR clock synchronization is removed, this has been superseeded
           be the STP clock synchronization.  And it always has been
           "interesting" code..

      Pull KVM leftovers from Radim Krčmář:
       "This is a combination of two pull requests for 4.7-rc8 that were not
        merged due to looking hairy.  I have changed the tag message to focus
        on circumstances of contained reverts as they were likely the reason
        behind rejection.
        This merge introduces three patches that are later reverted,
         - Switching of MSR_TSC_AUX in SVM was thought to cause a host
           misbehavior, but it was later cleared of those doubts and the patch
           moved code to a hot path, so we reverted it.  That patch also
           needed a fix for 32 bit builds and both were reverted in one go.
         - Al Viro noticed that a fix for a leak in an error path was not
           valid with the given API and provided a better fix, so the original
           patch was reverted.
        Then there are two VMX fixes that move code around because VMCS was
        not accessed between vcpu_load() and vcpu_put(), a simple ARM VHE fix,
        and two one-liners for PML and MTRR"

      Pull perf updates from Ingo Molnar:
       "With over 300 commits it's been a busy cycle - with most of the work
        concentrated on the tooling side (as it should).
        The main kernel side enhancements were:
         - Add per event callchain limit: Recently we introduced a sysctl to
           tune the max-stack for all events for which callchains were
             $ sysctl kernel.perf_event_max_stack
             kernel.perf_event_max_stack = 127
           Now this patch introduces a way to configure this per event, i.e.
           this becomes possible:
             $ perf record -e sched:*/max-stack=2/ -e block:*/max-stack=10/ -a
           allowing finer tuning of how much buffer space callchains use.
           This uses an u16 from the reserved space at the end, leaving
           another u16 for future use.
           There has been interest in even finer tuning, namely to control the
           max stack for kernel and userspace callchains separately.  Further
           discussion is needed, we may for instance use the remaining u16 for
           that and when it is present, assume that the sample_max_stack
           introduced in this patch applies for the kernel, and the u16 left
           is used for limiting the userspace callchain (Arnaldo Carvalho de
         - Optimize AUX event (hardware assisted side-band event) delivery
           (Kan Liang)
         - Rework Intel family name macro usage (this is partially x86 arch
           work) (Dave Hansen)
         - Refine and fix Intel LBR support (David Carrillo-Cisneros)
         - Add support for Intel 'TopDown' events (Andi Kleen)
         - Intel uncore PMU driver fixes and enhancements (Kan Liang)
         - ... other misc changes.
        Here's an incomplete list of the tooling enhancements (but there's
        much more, see the shortlog and the git log for details):
         - Support cross unwinding, i.e.  collecting '--call-graph dwarf'
           perf.data files in one machine and then doing analysis in another
           machine of a different hardware architecture.  This enables, for
           instance, to do:
             $ perf record -a --call-graph dwarf
           on a x86-32 or aarch64 system and then do 'perf report' on it on a
           x86_64 workstation (He Kuang)
         - Allow reading from a backward ring buffer (one setup via
           sys_perf_event_open() with perf_event_attr.write_backward = 1)
           (Wang Nan)
         - Finish merging initial SDT (Statically Defined Traces) support, see
           cset comments for details about how it all works (Masami Hiramatsu)
         - Support attaching eBPF programs to tracepoints (Wang Nan)
         - Add demangling of symbols in programs written in the Rust language
           (David Tolnay)
         - Add support for tracepoints in the python binding, including an
           example, that sets up and parses sched:sched_switch events,
           tools/perf/python/tracepoint.py (Jiri Olsa)
         - Introduce --stdio-color to set up the color output mode selection
           in 'annotate' and 'report', allowing emit color escape sequences
           when redirecting the output of these tools (Arnaldo Carvalho de
         - Add 'callindent' option to 'perf script -F', to indent the Intel PT
           call stack, making this output more ftrace-like (Adrian Hunter,
           Andi Kleen)
         - Allow dumping the object files generated by llvm when processing
           eBPF scriptlet events (Wang Nan)

      This reverts commit e083a21f.
      Not needed at all, tools/perf/util/perf_regs.h, included via:
        #include "perf_regs.h"
      Should have a definition for PERF_REGS_MAX, and since this is dependent
      on HAVE_PERF_REGS_SUPPORT, fixes the build on powerpc, noticed by trying
      to cross compile this from ubuntu16.04 with a locally build libz &
      elfutils pair, since those are not available in multilib packages.
