Subject: drm/nouveau/gr/gf100-gf119: modify max_ways_evict where required
Git-commit: c4a2b6385dd4a32759acf8e7884acd1115054887
Patch-mainline: v4.18-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

I don't think this is done after Fermi, NVGPU used to do it but removed
the code, and I've not seen RM traces touching it either.
