I'm guessing the entire pile goes in through some other tree. If so:

Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch>

If you want this to land through maintainer trees, then we need a
per-driver split (since aside from amdgpu and radeon they're all different
subtrees).

btw the two kmap calls in drm you highlight in the cover letter should
also be convertible to kmap_thread. We only hold vmalloc mappings for a
longer time (or it'd be quite a driver bug). So if you want maybe throw
those two as two additional patches on top, and we can do some careful
review & testing for them.
