      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.
