From: Thierry Reding <treding at nvidia.com> Export some more of the helpers in order to allow drivers to more fine- grainedly select which helpers to use. This gives drivers an easy way to reuse a lot of the code in the helpers while at the same time allowing them to provide their own implementation for other functions in struct dma_buf_ops.

From: Dave Airlie <airlied at redhat.com> [ Upstream commit a0cecc23cfcbf2626497a8c8770856dd56b67917 ] This patch does more harm than good, as it breaks both Xwayland and gnome-shell with X11. Xwayland requires DRI3 & DRI3 requires PRIME. X11 crash for obscure double-free reason which are hard to debug (starting X11 by hand doesn't trigger the crash). I don't see an apparent

Several GEM and PRIME callbacks have been deprecated in favor of per-instance GEM object functions. Remove the callbacks as they are now unused. The only exception is .gem_prime_mmap, which is still in use by several drivers. What is also gone is gem_vm_ops in struct drm_driver. All drivers now use struct drm_gem_object_funcs.vm_ops instead. While at it, the patch also improves error handling

Add max_segment argument to drm_prime_pages_to_sg(). When set pass it through to the __sg_alloc_table_from_pages() call, otherwise use SCATTERLIST_MAX_SEGMENT. Also add max_segment field to drm driver and pass it to drm_prime_pages_to_sg() calls in drivers and helpers. v2: place max_segment in drm driver not gem object. v3: move max_segment next to the other gem fields.
