Subject: [PATCH 3.12 047/235] drm/gma500: Add compat ioctl

From: Patrik Jakobsson <patrik.r.jakobsson@...il.com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

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.
