Tvrtko Ursulin 5602452e4c drm/i915: Use __sg_alloc_table_from_pages for userptr allocations ... With the addition of __sg_alloc_table_from_pages we can control the maximum coalescing size and eliminate a separate path for allocating backing store here. Similar to 871dfbd67d ("drm/i915: Allow compaction upto SWIOTLB max segment size") this enables more compact sg lists to be created and so has a beneficial effect on workloads with many and/or large objects of this class. v2: * Rename helper to i915_sg_segment_size and fix swiotlb override. * Commit message update. v3: * Actually include the swiotlb override fix. v4: * Regroup parameters a bit. (Chris Wilson) v5: * Rebase for swiotlb_max_segment. * Add DMA map failure handling as in abb0deacb5 ("drm/i915: Fallback to single PAGE_SIZE segments for DMA remapping"). v6: Handle swiotlb_max_segment() returning 1. (Joonas Lahtinen) v7: Rebase. v8: Commit spelling fix.
