Subject: [PATCH] drm/i915: Try a minimal attempt to insert the whole object for relocations
Git-commit: 3c755c5b56a79cf0a2681abf705cebfb10737db2
Patch-mainline: v4.15-rc1
References: FATE#322643 bsc#1055900
As we have a lightweight fallback to insert a single page into the
aperture, try to avoid any heavier evictions when attempting to insert
the entire object.
