Subject: drm/nouveau/fb/gm200: enable NV_PFB_MMU_CTRL_USE_FULL_COMP_TAG_LINE
where appropriate
Git-commit: bda9e379f61f937af7ee9b2a32d54bc50a94cd80
Patch-mainline: v4.15-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
To avoid wasting compression tags when using 64KiB pages, we need to
enable this so we can select between upper/lower comptagline in PTEs.
