4.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Patrik Jakobsson <patrik.r.jakobs...@gmail.com> commit 0a97c81a9717431e6c57ea845b59c3c345edce67 upstream. Hook up drm_compat_ioctl to support 32-bit userspace on 64-bit kernels. It turns out that N2600 and N2800 comes with 64-bit enabled. We previously assumed there where no such systems out there.
