       "This is another round of bug fixing and cleanup. This time the focus
        is on the driver pattern to use mmu notifiers to monitor a VA range.
        This code is lifted out of many drivers and hmm_mirror directly into
        the mmu_notifier core and written using the best ideas from all the
        driver implementations.
        This removes many bugs from the drivers and has a very pleasing

         - A shared branch with RDMA reworking the RDMA ODP implementation
         - New mmu_interval_notifier API. This is focused on the use case of
           monitoring a VA and simplifies the process for drivers
         - A common seq-count locking scheme built into the
           mmu_interval_notifier API usable by drivers that call
           get_user_pages() or hmm_range_fault() with the VA range
         - Conversion of mlx5 ODP, hfi1, radeon, nouveau, AMD GPU, and Xen
           GntDev drivers to the new API. This deletes a lot of wonky driver

      Dave Airlie authored
      Graphics APIs like OpenGL 4.4 and Vulkan require the graphics driver
      to provide coherent graphics memory, meaning that the GPU sees any
      content written to the coherent memory on the next GPU operation that
      touches that memory, and the CPU sees any content written by the GPU
      to that memory immediately after any fence object trailing the GPU
      operation is signaled.
      Paravirtual drivers that otherwise require explicit synchronization
      needs to do this by hooking up dirty tracking to pagefault handlers
      and buffer object validation.
      Provide mm helpers needed for this and that also allow for huge pmd-
      and pud entries (patch 1-3), and the associated vmwgfx code (patch 4-7).
      The code has been tested and exercised by a tailored version of mesa
      where we disable all explicit synchronization and assume graphics memory
      is coherent. The performance loss varies of course; a typical number is
      around 5%.

      Linus Torvalds authored
      Pull tracing updates from Steven Rostedt:
       "New tracing features:
         - New PERMANENT flag to ftrace_ops when attaching a callback to a
           As /proc/sys/kernel/ftrace_enabled when set to zero will disable
           all attached callbacks in ftrace, this has a detrimental impact on
           live kernel tracing, as it disables all that it patched. If a
           ftrace_ops is registered to ftrace with the PERMANENT flag set, it
           will prevent ftrace_enabled from being disabled, and if
           ftrace_enabled is already disabled, it will prevent a ftrace_ops
           with PREMANENT flag set from being registered.
         - New register_ftrace_direct().
           As eBPF would like to register its own trampolines to be called by
           the ftrace nop locations directly, without going through the ftrace
           trampoline, this function has been added. This allows for eBPF
           trampolines to live along side of ftrace, perf, kprobe and live
           patching. It also utilizes the ftrace enabled_functions file that
           keeps track of functions that have been modified in the kernel, to
           allow for security auditing.
         - Allow for kernel internal use of ftrace instances.
           Subsystems in the kernel can now create and destroy their own
           tracing instances which allows them to have their own tracing
           buffer, and be able to record events without worrying about other
           users from writing over their data.
         - New seq_buf_hex_dump() that lets users use the hex_dump() in their
           seq_buf usage.
         - Notifications now added to tracing_max_latency to allow user space
           to know when a new max latency is hit by one of the latency
         - Wider spread use of generic compare operations for use of bsearch
           and friends.
         - More synthetic event fields may be defined (32 up from 16)
         - Use of xarray for architectures with sparse system calls, for the
           system call trace events.
        This along with small clean ups and fixes"

      net: wireless: intel: iwlwifi: fix GRO_NORMAL packet stalling · b167191e
      Alexander Lobakin authored
      Commit 6570bc79 ("net: core: use listified Rx for GRO_NORMAL in
      napi_gro_receive()") has applied batched GRO_NORMAL packets processing
      to all napi_gro_receive() users, including mac80211-based drivers.
      However, this change has led to a regression in iwlwifi driver [1][2] as
      it is required for NAPI users to call napi_complete_done() or
      napi_complete() and the end of every polling iteration, whilst iwlwifi
      doesn't use NAPI scheduling at all and just calls napi_gro_flush().
      In that particular case, packets which have not been already flushed
      from napi->rx_list stall in it until at least next Rx cycle.
      Fix this by adding a manual flushing of the list to iwlwifi driver right
      before napi_gro_flush() call to mimic napi_complete() logics.
      I prefer to open-code gro_normal_list() rather than exporting it for 2
      * to prevent from using it and napi_gro_flush() in any new drivers,
        as it is the *really* bad way to use NAPI that should be avoided;
      * to keep gro_normal_list() static and don't lose any CC optimizations.
      I also don't add the "Fixes:" tag as the mentioned commit was only a
      trigger that only exposed an improper usage of NAPI in this particular

      Pull driver core updates from Greg KH:
       "Here is the "big" set of driver core patches for 5.5-rc1
        There's a few minor cleanups and fixes in here, but the majority of
        the patches in here fall into two buckets:
         - debugfs api cleanups and fixes
         - driver core device link support for boot dependancy issues
        The debugfs api cleanups are working to slowly refactor the debugfs
        apis so that it is even harder to use incorrectly. That work has been
        happening for the past few kernel releases and will continue over
        time, it's a long-term project/goal
        The driver core device link support missed 5.4 by just a bit, so it's
        been sitting and baking for many months now. It's from Saravana Kannan
        to help resolve the problems that DT-based systems have at boot time
        with dependancy graphs and kernel modules. Turns out that no one has
        actually tried to build a generic arm64 kernel with loads of modules
        and have it "just work" for a variety of platforms (like a distro
        kernel). The big problem turned out to be a lack of dependency
        information between different areas of DT entries, and the work here
        resolves that problem and now allows devices to boot properly, and
        quicker than a monolith kernel.
        All of these patches have been in linux-next for a long time with no
        reported issues"
