From a65adaf8a834504a4acdc0deca7fa790771add8a Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Mon, 9 Oct 2017 09:43:57 +0100 Subject: drm/i915: Track user GTT faulting per-vma We don't wish to refault the entire object (other vma) when unbinding one partial vma. To do this track which vma have been faulted into the user's address space. v2: Use a local vma_offset to tidy up a multiline unmap_mapping_range().
