The commit d931589c01a2 ("drm/exynos: remove DRM_EXYNOS_GEM_MAP_OFFSET ioctl") removed it same with the ioctl that this patch adds. The reason that removed DRM_EXYNOS_GEM_MAP_OFFSET was we could use DRM_IOCTL_MODE_MAP_DUMB. Both did exactly same thing.
Now we again will revive it as DRM_EXYNOS_GEM_MAP because of render node. DRM_IOCTL_MODE_MAP_DUMB isn't permitted in render node.

Right. With Daniel patch, DRM_UNLOCKED flag isn't needed anymore for driver specific ioctls.
I found it on next-20151012, do you want v2 patch that DRM_UNLOCKED flag is dropped?
It'd be better to drop the flag for cleanup. Anyway, I can do it.
