      Fix kmalloc slab creation sequence · a9730fca
      Christoph Lameter authored
      This patch restores the slab creation sequence that was broken by commit
      4066c33d and also reverts the portions that introduced the
      KMALLOC_LOOP_XXX macros. Those can never really work since the slab creation
      is much more complex than just going from a minimum to a maximum number.
      The latest upstream kernel boots cleanly on my machine with a 64 bit x86
      configuration under KVM using either SLAB or SLUB.
      Fixes: 4066c33d
       ("support the slub_debug boot option")

      Linus Torvalds authored
      Pull libnvdimm subsystem from Dan Williams:
       "The libnvdimm sub-system introduces, in addition to the
        libnvdimm-core, 4 drivers / enabling modules:
          Instantiates an "nvdimm bus" with the core and registers memory
          devices (NVDIMMs) enumerated by the ACPI 6.0 NFIT (NVDIMM Firmware
          Interface table).
          After registering NVDIMMs the NFIT driver then registers "region"
          devices.  A libnvdimm-region defines an access mode and the
          boundaries of persistent memory media.  A region may span multiple
          NVDIMMs that are interleaved by the hardware memory controller.  In
          turn, a libnvdimm-region can be carved into a "namespace" device and
          bound to the PMEM or BLK driver which will attach a Linux block
          device (disk) interface to the memory.
          Initially merged in v4.1 this driver for contiguous spans of
          persistent memory address ranges is re-worked to drive
          PMEM-namespaces emitted by the libnvdimm-core.
          In this update the PMEM driver, on x86, gains the ability to assert
          that writes to persistent memory have been flushed all the way
          through the caches and buffers in the platform to persistent media.
          See memcpy_to_pmem() and wmb_pmem().
          This new driver enables access to persistent memory media through
          "Block Data Windows" as defined by the NFIT.  The primary difference
          of this driver to PMEM is that only a small window of persistent
          memory is mapped into system address space at any given point in
          Per-NVDIMM windows are reprogrammed at run time, per-I/O, to access
          different portions of the media.  BLK-mode, by definition, does not
          support DAX.
          This is a library, optionally consumed by either PMEM or BLK, that
          converts a byte-accessible namespace into a disk with atomic sector
          update semantics (prevents sector tearing on crash or power loss).
          The sinister aspect of sector tearing is that most applications do
          not know they have a atomic sector dependency.  At least today's
          disk's rarely ever tear sectors and if they do one almost certainly
          gets a CRC error on access.  NVDIMMs will always tear and always
          silently.  Until an application is audited to be robust in the
          presence of sector-tearing the usage of BTT is recommended.

      Pull cgroup updates from Tejun Heo:
       - threadgroup_lock got reorganized so that its users can pick the
         actual locking mechanism to use.  Its only user - cgroups - is
         updated to use a percpu_rwsem instead of per-process rwsem.
         This makes things a bit lighter on hot paths and allows cgroups to
         perform and fail multi-task (a process) migrations atomically.
         Multi-task migrations are used in several places including the
         unified hierarchy.
       - Delegation rule and documentation added to unified hierarchy.  This
         will likely be the last interface update from the cgroup core side
         for unified hierarchy before lifting the devel mask.
       - Some groundwork for the pids controller which is scheduled to be
         merged in the coming devel cycle.

      Linus Torvalds authored
      Pull tracing updates from Steven Rostedt:
       "This patch series contains several clean ups and even a new trace
        clock "monitonic raw".  Also some enhancements to make the ring buffer
        even faster.  But the biggest and most noticeable change is the
        renaming of the ftrace* files, structures and variables that have to
        deal with trace events.
        Over the years I've had several developers tell me about their
        confusion with what ftrace is compared to events.  Technically,
        "ftrace" is the infrastructure to do the function hooks, which include
        tracing and also helps with live kernel patching.  But the trace
        events are a separate entity altogether, and the files that affect the
        trace events should not be named "ftrace".  These include:
          include/trace/ftrace.h         ->    include/trace/trace_events.h
          include/linux/ftrace_event.h   ->    include/linux/trace_events.h
        Also, functions that are specific for trace events have also been renamed:
          ftrace_print_*()               ->    trace_print_*()
          (un)register_ftrace_event()    ->    (un)register_trace_event()
          ftrace_event_name()            ->    trace_event_name()
          ftrace_trigger_soft_disabled() ->    trace_trigger_soft_disabled()
          ftrace_define_fields_##call()  ->    trace_define_fields_##call()
          ftrace_get_offsets_##call()    ->    trace_get_offsets_##call()
        Structures have been renamed:
          ftrace_event_file              ->    trace_event_file
          ftrace_event_{call,class}      ->    trace_event_{call,class}
          ftrace_event_buffer            ->    trace_event_buffer
          ftrace_subsystem_dir           ->    trace_subsystem_dir
          ftrace_event_raw_##call        ->    trace_event_raw_##call
          ftrace_event_data_offset_##call->    trace_event_data_offset_##call
          ftrace_event_type_funcs_##call ->    trace_event_type_funcs_##call
        And a few various variables and flags have also been updated.
        This has been sitting in linux-next for some time, and I have not
        heard a single complaint about this rename breaking anything.  Mostly
        because these functions, variables and structures are mostly internal
        to the tracing system and are seldom (if ever) used by anything
        external to that"

       "This isn't my 4.2 pull request (yet).  I found a few more bugs that I
        would have sent to fix 4.1, but since 4.1 is already out, I'm sending
        this before sending my 4.2 request (which is ready to go).
        After fixing the previous filter issue reported by Vince Weaver, I
        could not come up with a situation where the operand counter (cnt)
        could go below zero, so I added a WARN_ON_ONCE(cnt < 0).  Vince was
        able to trigger that warn on with his fuzzer test, but didn't have a
        filter input that caused it.
        Later, Sasha Levin was able to trigger that same warning, and was able
        to give me the filter string that triggered it.  It was simply a
        single operation ">".
        I wrapped the filtering code in a userspace program such that I could
        single step through the logic.  With a single operator the operand
        counter can legitimately go below zero, and should be reported to the
        user as an error, but should not produce a kernel warning.  The
        WARN_ON_ONCE(cnt < 0) should be just a "if (cnt < 0) break;" and the
        code following it will produce the error message for the user.
        While debugging this, I found that there was another bug that let the
        pointer to the filter string go beyond the filter string.  This too
        was fixed.
        Finally, there was a typo in a stub function that only gets compiled
        if trace events is disabled but tracing is enabled (I'm not even sure
        that's possible)"

       "This is the main drm pull request for v4.2.
        I've one other new driver from freescale on my radar, it's been posted
        and reviewed, I'd just like to get someone to give it a last look, so
        maybe I'll send it or maybe I'll leave it.
        There is no major nouveau changes in here, Ben was working on
        something big, and we agreed it was a bit late, there wasn't anything
        else he considered urgent to merge.
        There might be another msm pull for some bits that are waiting on
        arm-soc, I'll see how we time it.
        This touches some "of" stuff, acks are in place except for the fixes
        to the build in various configs,t hat I just applied.
        New drivers:
            - virtio-gpu:
                      KMS only pieces of driver for virtio-gpu in qemu.
                      This is just the first part of this driver, enough to run
                      unaccelerated userspace on. As qemu merges more we'll start
                      adding the 3D features for the virgl 3d work.
            - amdgpu:
                      a new driver from AMD to driver their newer GPUs. (VI+)
                      It contains a new cleaner userspace API, and is a clean
                      break from radeon moving forward, that AMD are going to
                      concentrate on. It also contains a set of register headers
                      auto generated from AMD internal database.
            - atomic modesetting API completed, enabled by default now.
            - Add support for mode_id blob to atomic ioctl to complete interface.
            - bunch of Displayport MST fixes

      Greg Kroah-Hartman authored
      The wilc1000 has just too many build warnings to be able to enable it
      for the 4.2 release.  Given that there have not been any patches
      submitted to properly fix these obvious errors, I'm going to disable it
      for now.  I will enable it back when the build warning fixes are
      submitted, or, if that never happens, I will remove it from the tree.
