-Subject: [PATCH] drm/i915: Dont enable CS_PARSER_ERROR interrupts at all

-We stopped handling them in

- drm/i915: Stop gathering error states for CS error interrupts
-
-but just clearing is apparently not enough: A sufficiently dead gpu
-left behind by firmware (*cough* coreboot *cough*) can keep the gpu in
-an endless loop of such interrupts, eventually leading to the nmi
-firing. And definitely to what looks like a machine hang.
-
-Since we don't even enable these interrupts on gen5+ let's do the same
-on earlier platforms.
