[Mesa-dev] [PATCH] i965/screen: MOD_FORMAT_Y_TILED is only supported by gen9+

[Mario Kleiner]

At least that's what the Linux 4.18 i915 drm/kms driver
thinks, and the disagreement between kms and Mesa leads to
pageflipping failure with X-Server 1.20's dmabuf modifiers
enabled modesetting-ddx, at least as tested on a gen 7
Ivybridge system.
