       "In this release, we hoisted as much of XFS' writeback code into iomap
        as was practicable, refactored the unshare file data function, added

      Pull hmm updates from Jason Gunthorpe:
       "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
        diffstat. More drivers can still be converted, but that is for another
        cycle.
      
         - 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
           code.
      
         - Two improvements for hmm_range_fault(), from testing done by Ralph"

      Pull generic ioremap support from Christoph Hellwig:
       "This adds the remaining bits for an entirely generic ioremap and
        iounmap to lib/ioremap.c. To facilitate that, it cleans up the giant
        mess of weird ioremap variants we had with no users outside the arch
        code.
      
        For now just the three newest ports use the code, but there is more
        than a handful others that can be converted without too much work.
      
        Summary:

      Merge branch 'vmwgfx-coherent' of git://people.freedesktop.org/~thomash/linux into drm-next · 0a6cad5d
      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
           function.
      
           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
           tracers.
      
         - 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.
