       "Mostly refactoring/clean-up:
      
         - CPU ops and PSCI (Power State Coordination Interface) refactoring
           following the merging of the arm64 ACPI support, together with
           handling of Trusted (secure) OS instances
      
         - Using fixmap for permanent FDT mapping, removing the initial dtb
           placement requirements (within 512MB from the start of the kernel
           image).  This required moving the FDT self reservation out of the
           memreserve processing
      
         - Idmap (1:1 mapping used for MMU on/off) handling clean-up
      
         - Removing flush_cache_all() - not safe on ARM unless the MMU is off.
           Last stages of CPU power down/up are handled by firmware already
      
         - "Alternatives" (run-time code patching) refactoring and support for
           immediate branch patching, GICv3 CPU interface access
      
         - User faults handling clean-up
      
        And some fixes:
      
         - Fix for VDSO building with broken ELF toolchains
      
         - Fix another case of init_mm.pgd usage for user mappings (during
           ASID roll-over broadcasting)
      
         - Fix for FPSIMD reloading after CPU hotplug
      
         - Fix for missing syscall trace exit
      
         - Workaround for .inst asm bug

      Pull first batch of KVM updates from Paolo Bonzini:
       "The bulk of the changes here is for x86.  And for once it's not for
        silicon that no one owns: these are really new features for everyone.
      
        Details:
      
         - ARM:
              several features are in progress but missed the 4.2 deadline.
              So here is just a smattering of bug fixes, plus enabling the
              VFIO integration.
      
         - s390:
              Some fixes/refactorings/optimizations, plus support for 2GB
              pages.
      
         - x86:
              * host and guest support for marking kvmclock as a stable
                scheduler clock.
              * support for write combining.
              * support for system management mode, needed for secure boot in
                guests.
              * a bunch of cleanups required for the above
              * support for virtualized performance counters on AMD
              * legacy PCI device assignment is deprecated and defaults to "n"
                in Kconfig; VFIO replaces it
      
              On top of this there are also bug fixes and eager FPU context
              loading for FPU-heavy guests.
      
         - Common code:
              Support for multiple address spaces; for now it is used only for
              x86 SMM but the s390 folks also have plans"
      
      * tag 'for-linus' of git://git.kernel.org/pub/scm/virt/kvm/kvm: (124 commits)

      Linus Torvalds authored
      Pull IOMMU updates from Joerg Roedel:
       "This time with bigger changes than usual:
      
         - A new IOMMU driver for the ARM SMMUv3.
      
           This IOMMU is pretty different from SMMUv1 and v2 in that it is
           configured through in-memory structures and not through the MMIO
           register region.  The ARM SMMUv3 also supports IO demand paging for
           PCI devices with PRI/PASID capabilities, but this is not
           implemented in the driver yet.
      
         - Lots of cleanups and device-tree support for the Exynos IOMMU
           driver.  This is part of the effort to bring Exynos DRM support
           upstream.
      
         - Introduction of default domains into the IOMMU core code.
      
           The rationale behind this is to move functionalily out of the IOMMU
           drivers to common code to get to a unified behavior between
           different drivers.  The patches here introduce a default domain for
           iommu-groups (isolation groups).
      
           A device will now always be attached to a domain, either the
           default domain or another domain handled by the device driver.  The
           IOMMU drivers have to be modified to make use of that feature.  So
           long the AMD IOMMU driver is converted, with others to follow.
      
         - Patches for the Intel VT-d drvier to fix DMAR faults that happen
           when a kdump kernel boots.
      
           When the kdump kernel boots it re-initializes the IOMMU hardware,
           which destroys all mappings from the crashed kernel.  As this
           happens before the endpoint devices are re-initialized, any
           in-flight DMA causes a DMAR fault.  These faults cause PCI master
           aborts, which some devices can't handle properly and go into an
           undefined state, so that the device driver in the kdump kernel
           fails to initialize them and the dump fails.
      
           This is now fixed by copying over the mapping structures (only
           context tables and interrupt remapping tables) from the old kernel
           and keep the old mappings in place until the device driver of the
           new kernel takes over.  This emulates the the behavior without an
           IOMMU to the best degree possible.
      
         - A couple of other small fixes and cleanups"

       "JFFS2:
         - fix a theoretical unbalanced locking issue; the lock handling was a
           bit unclean, but AFAICT, it didn't actually lead to real deadlocks
      
        NAND:
         - brcmnand driver: new driver supporting NAND controller found
           originally on Broadcom STB SoCs (BCM7xxx), but now also found on
           BCM63xxx, iProc (e.g., Cygnus, BCM5301x), BCM3xxx, and more
      
         - begin factoring out BBT code so it can be shared between
           traditional (parallel) NAND drivers and upcoming SPI NAND drivers
           (WIP)
      
         - add common DT-based init support, so nand_base can pick up some
           flash properties automatically, using established common NAND DT
           properties
      
         - mxc_nand: support 8-bit ECC
      
         - pxa3xx_nand:
           * fix build for ARM64
           * use a jiffies-based timeout
      
        SPI NOR:
         - add a few new IDs
      
         - clear out some unnecessary entries
      
         - make sure SECT_4K flags are correct for all (?) entries
      
        Core:
         - fix mtd->usecount race conditions (BUG_ON())
      
         - switch to modern PM ops

      Linus Torvalds authored
      Pull clkdev updates from Russell King:
       "This series addresses some breakage in clkdev caused by a previous
        patch set from the clk tree which introduced per-user clk structures.
        This basically renamed the existing 'struct clk' to 'struct clk_hw',
        and introduced a new 'struct clk'.
      
        This change will break anyone using clk_add_alias() with the common
        clk code enabled.  Thankfully, the intersection of users of
        clk_add_alias() and those using the common clk code is practically
        zero, but this is something which should be fixed to keep the code
        sane.
      
        The problem is that clk_add_alias() does this:
      
              r = clk_get(...);
              l = clkdev_alloc(r, ...);
              clk_put(...);
      
        which causes the alias to store a pointer to 'r', which has been
        freed.
      
        The original patch set tried to work around this problem incorrectly -
        at clk_get() time, it tried to convert the struct clk to a struct
        clk_hw, and then creating a new struct clk from that.  Clearly, if the
        original struct clk has been freed, then we have a use-after-free bug.
      
        We have other places in the tree which do something similar, so this
        series also addresses those locations too.
      
        This series addresses this problem by converting clkdev to store and
        use the clk_hw pointer.  This allows clk_get() to only have to create
        it's per-user struct clk from the clk_hw.  We can also get to the
        desired clk_hw at clk_add_alias() or clk lookup creation time, when
        the struct clk is "alive".
      
        We also perform some cleanups of the code:
      
         - replacing looped calls to clkdev_add() with clkdev_add_table()
      
         - replacing open-coded lookup allocation (which should have been
           using clkdev_alloc()) and subsequent clkdev_add() with
           clkdev_create()
      
         - replacing open-coded clk_add_alias() with clk_add_alias()"

       "The rework of backlight interface selection API from Hans de Goede
        stands out from the number of commits and the number of affected
        places perspective.  The cpufreq core fixes from Viresh Kumar are
        quite significant too as far as the number of commits goes and because
        they should reduce CPU online/offline overhead quite a bit in the
        majority of cases.
      
        From the new featues point of view, the ACPICA update (to upstream
        revision 20150515) adding support for new ACPI 6 material to ACPICA is
        the one that matters the most as some new significant features will be
        based on it going forward.  Also included is an update of the ACPI
        device power management core to follow ACPI 6 (which in turn reflects
        the Windows' device PM implementation), a PM core extension to support
        wakeup interrupts in a more generic way and support for the ACPI _CCA
        device configuration object.
      
        The rest is mostly fixes and cleanups all over and some documentation
        updates, including new DT bindings for Operating Performance Points.
      
        There is one fix for a regression introduced in the 4.1 cycle, but it
        adds quite a number of lines of code, it wasn't really ready before
        Thursday and you were on vacation, so I refrained from pushing it on
        the last minute for 4.1.
      
        Specifics:
      
         - ACPICA update to upstream revision 20150515 including basic support
           for ACPI 6 features: new ACPI tables introduced by ACPI 6 (STAO,
           XENV, WPBT, NFIT, IORT), changes related to the other tables (DTRM,
           FADT, LPIT, MADT), new predefined names (_BTH, _CR3, _DSD, _LPI,
           _MTL, _PRR, _RDI, _RST, _TFP, _TSN), fixes and cleanups (Bob Moore,
           Lv Zheng).
      
         - ACPI device power management core code update to follow ACPI 6
           which reflects the ACPI device power management implementation in
           Windows (Rafael J Wysocki).
      
         - rework of the backlight interface selection logic to reduce the
           number of kernel command line options and improve the handling of
           DMI quirks that may be involved in that and to make the code
           generally more straightforward (Hans de Goede).
      
         - fixes for the ACPI Embedded Controller (EC) driver related to the
           handling of EC transactions (Lv Zheng).
      
         - fix for a regression related to the ACPI resources management and
           resulting from a recent change of ACPI initialization code ordering
           (Rafael J Wysocki).
      
         - fix for a system initialization regression related to ACPI
           introduced during the 3.14 cycle and caused by running the code
           that switches the platform over to the ACPI mode too early in the
           initialization sequence (Rafael J Wysocki).
      
         - support for the ACPI _CCA device configuration object related to
           DMA cache coherence (Suravee Suthikulpanit).

           be generated occasionally on return to user space after resume from
           ACPI-based suspend-to-RAM on 32-bit x86 (Ingo Molnar).
      
         - fix to make the suspend core code return -EBUSY consistently in all
           cases when system suspend is aborted due to wakeup detection (Ruchi
           Kandoi).
      
         - support for automated device wakeup IRQ handling allowing drivers
           to make their PM support more starightforward (Tony Lindgren).

         - powernv/pseries cpuidle driver update (Shilpasri G Bhat).
      
         - cpufreq core fixes related to CPU online/offline that should reduce
           the overhead of these operations quite a bit, unless the CPU in
           question is physically going away (Viresh Kumar, Saravana Kannan).
      
         - serialization of cpufreq governor callbacks to avoid race
           conditions in some cases (Viresh Kumar).
      
         - intel_pstate driver fixes and cleanups (Doug Smythies, Prarit
           Bhargava, Joe Konno).
      
         - cpufreq driver (arm_big_little, cpufreq-dt, qoriq) updates (Sudeep

           first patch in that series had to go into stable.  This makes the
           locking much more fine-grained (get rid of the "big GPIO lock(s)"

              device using acpi_dev_gpio_irq_get()
            * merge some dependent I2C changes exploiting this.
            * support the ARM X-Gene GPIO standby driver.
      
         - make it possible for the generic GPIO driver to read back the value
           set registers to reflect current status.
      
         - loads of OMAP IRQ handling fixes.
      
         - incremental improvements to Kona, max732x, OMAP, MXC, RCAR,
           PCA953x, STP-XWAY, PCF857x, Crystalcove, TB10x.

      KVM: s390: clear floating interrupt bitmap and parameters · f2ae45ed
      Jens Freimann authored
      commit 6d3da241 ("KVM: s390: deliver floating interrupts in order
      of priority") introduced a regression for the reset handling.
      
      We don't clear the bitmap of pending floating interrupts
      and interrupt parameters. This could result in stale interrupts
      even after a reset. Let's fix this by clearing the pending bitmap
      and the parameters for service and machine check interrupts.

      Wei Huang authored
      This patch defines a new function pointer struct (kvm_pmu_ops) to
      support vPMU for both Intel and AMD. The functions pointers defined in
      this new struct will be linked with Intel and AMD functions later. In the
      meanwhile the struct that maps from event_sel bits to PERF_TYPE_HARDWARE
      events is renamed and moved from Intel specific code to kvm_host.h as a
      common struct.

      Merge branch 'x86-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip · d70b3ef5
      Linus Torvalds authored
      Pull x86 core updates from Ingo Molnar:
       "There were so many changes in the x86/asm, x86/apic and x86/mm topics
        in this cycle that the topical separation of -tip broke down somewhat -
        so the result is a more traditional architecture pull request,
        collected into the 'x86/core' topic.
      
        The topics were still maintained separately as far as possible, so
        bisectability and conceptual separation should still be pretty good -
        but there were a handful of merge points to avoid excessive
        dependencies (and conflicts) that would have been poorly tested in the
        end.
      
        The next cycle will hopefully be much more quiet (or at least will
        have fewer dependencies).
      
        The main changes in this cycle were:
      
         * x86/apic changes, with related IRQ core changes: (Jiang Liu, Thomas
           Gleixner)
      
           - This is the second and most intrusive part of changes to the x86
             interrupt handling - full conversion to hierarchical interrupt
             domains:
      
                [IOAPIC domain]   -----
                                       |
                [MSI domain]      --------[Remapping domain] ----- [ Vector domain ]
                                       |   (optional)          |
                [HPET MSI domain] -----                        |
                                                               |
                [DMAR domain]     -----------------------------
                                                               |
                [Legacy domain]   -----------------------------
      
             This now reflects the actual hardware and allowed us to distangle
             the domain specific code from the underlying parent domain, which
             can be optional in the case of interrupt remapping.  It's a clear
             separation of functionality and removes quite some duct tape
             constructs which plugged the remap code between ioapic/msi/hpet
             and the vector management.
      
           - Intel IOMMU IRQ remapping enhancements, to allow direct interrupt
             injection into guests (Feng Wu)
      
         * x86/asm changes:
      
           - Tons of cleanups and small speedups, micro-optimizations.  This
             is in preparation to move a good chunk of the low level entry
             code from assembly to C code (Denys Vlasenko, Andy Lutomirski,
             Brian Gerst)
      
           - Moved all system entry related code to a new home under
             arch/x86/entry/ (Ingo Molnar)
      
           - Removal of the fragile and ugly CFI dwarf debuginfo annotations.
             Conversion to C will reintroduce many of them - but meanwhile
             they are only getting in the way, and the upstream kernel does
             not rely on them (Ingo Molnar)
      
           - NOP handling refinements. (Borislav Petkov)
      
         * x86/mm changes:
      
           - Big PAT and MTRR rework: making the code more robust and
             preparing to phase out exposing direct MTRR interfaces to drivers -
             in favor of using PAT driven interfaces (Toshi Kani, Luis R
             Rodriguez, Borislav Petkov)
      
           - New ioremap_wt()/set_memory_wt() interfaces to support
             Write-Through cached memory mappings.  This is especially
             important for good performance on NVDIMM hardware (Toshi Kani)
      
         * x86/ras changes:
      
           - Add support for deferred errors on AMD (Aravind Gopalakrishnan)
      
             This is an important RAS feature which adds hardware support for
             poisoned data.  That means roughly that the hardware marks data
             which it has detected as corrupted but wasn't able to correct, as
             poisoned data and raises an APIC interrupt to signal that in the
             form of a deferred error.  It is the OS's responsibility then to
             take proper recovery action and thus prolonge system lifetime as
             far as possible.
      
           - Add support for Intel "Local MCE"s: upcoming CPUs will support
             CPU-local MCE interrupts, as opposed to the traditional system-
             wide broadcasted MCE interrupts (Ashok Raj)
      
           - Misc cleanups (Borislav Petkov)
      
         * x86/platform changes:
      
           - Intel Atom SoC updates
      
        ... and lots of other cleanups, fixlets and other changes - see the
        shortlog and the Git log for details"
