      drm: Remove SCATTERLIST_MAX_SEGMENT · 7a60c2dd
      Jason Gunthorpe authored
      Since commit 9a40401c ("lib/scatterlist: Do not limit max_segment to
      PAGE_ALIGNED values") the max_segment input to sg_alloc_table_from_pages()
      does not have to be any special value. The new algorithm will always
      create something less than what the user provides. Thus eliminate this
      confusing constant.
      
      - vmwgfx should use the HW capability, not mix in the OS page size for
        calling dma_set_max_seg_size()
      
      - i915 uses i915_sg_segment_size() both for sg_alloc_table_from_pages
        and for some open coded sgl construction. This doesn't change the value
        since rounddown(size, UINT_MAX) == SCATTERLIST_MAX_SEGMENT
      
      - drm_prime_pages_to_sg uses it as a default if max_segment is zero,
        UINT_MAX is fine to use directly.

      drm/atomic: Pass the full state to CRTC atomic begin and flush · f6ebe9f9
      Maxime Ripard authored
      The current atomic helpers have either their object state being passed as
      an argument or the full atomic state.
      
      The former is the pattern that was done at first, before switching to the
      latter for new hooks or when it was needed.
      
      Let's start convert all the remaining helpers to provide a consistent
      interface, starting with the CRTC's atomic_begin and atomic_flush.
      
      The conversion was done using the coccinelle script below, built tested on
      all the drivers and actually tested on vc4.

      drm/nouveau/ttm: Add limits.h · 95f4f40a
      Maxime Ripard authored
      It seems that a recent commit broke the nouveau compilation when swiotlb is
      disabled (which is the case on our ARM defconfig for example).
      
      Daniel says
      
      """
      Since the proper fix is maybe stuck in the usual "drm abuses swiotlb
      internals" bikeshed, maybe best if we push a fix to including limits.h
      in nouveau and call it done?
      """
      
      So let's go down the simplest path to fix our build, and goes back to it
      later if needed.

         - Prevent undefined behaviour in the timespec64_to_ns() conversion
           which is used for converting user supplied time input to
           nanoseconds. It lacked overflow protection.

      Pull char/misc fixes/removals from Greg KH:
       "Here's some small fixes for 5.10-rc2 and a big driver removal.
      
        The fixes are for some reported issues in the interconnect and
        coresight drivers, nothing major.
      
        The "big" driver removal is the MIC drivers have been asked to be
        removed as the hardware never shipped and Intel no longer wants to
        maintain something that no one can use. This is welcomed by many as
        the DMA usage of these drivers was "interesting" and the security
        people were starting to question some issues that were starting to be
        found in the codebase.
      
        Note, one of the subsystems for this driver, the "VOP" code, will
        probably come back in future kernel versions as it was looking to
        potentially solve some PCIe virtualization issues that a number of
        other vendors were wanting to solve. But as-is, this codebase didn't
        work for anyone else so no actual functionality is being removed.
      
        All of these have been in linux-next with no reported issues"

        earlier), and a much larger Documentation/ABI/ update to the files so
        they can be automatically parsed by our tools.
      
        The Documentation/ABI/ updates are just formatting issues, small ones
        to bring the files into parsable format, and have been acked by
        numerous subsystem maintainers and the documentation maintainer. I
        figured it was good to get this into 5.10-rc2 to help wih the merge
        issues that would arise if these were to stick in linux-next until
        5.11-rc1.
