Subject: drm/vgem: add compat_ioctl support
Git-commit: ad364f447e367a4b997cc75093600663caeedb68
Patch-mainline: v4.14-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

DRM drivers should supply a compat version if they're going to provide
an ioctl implementation at all. This can confuse 32-bit user space on a
64-bit system.
