   - vma_set_file helper to make vma->vm_file changing less brittle,
     acked by Andrew

  Core Changes:

   - dma-buf heaps improvements

   - pass full atomic modeset state to driver callbacks

   - shmem helpers: cached bo by default

   - cleanups for fbdev, fb-helpers

   - better docs for drm modes and SCALING_FITLER uapi

   - ttm: fix dma32 page pool regression

  Driver Changes:

   - multi-hop regression fixes for amdgpu, radeon, nouveau

   - lots of small amdgpu hw enabling fixes (display, pm, ...)

   - fixes for imx, mcde, meson, some panels, virtio, qxl, i915, all
     fairly minor

   - some cleanups for legacy drm/fbdev drivers"
