Chris Wilson 82d71e31ae drm/i915/gt: Poison GTT scratch pages ... Using a clear page for scratch means that we have relatively benign errors in case it is accidentally used, but that can be rather too benign for debugging. If we poison the scratch, ideally it quickly results in an obvious error. v2: Set each page individually just in case we are using highmem for our scratch page. v3: Pick a new scratch register as MI_STORE_REGISTER_MEM does not work with GPR0 on gen7, unbelievably. v4: Haswell still considers 3DPRIM a privileged register!
