Ok, merged patches 2-5 to drm-misc-next. Sorry for the delay, caught a
cold and was out of service past few days :-/

Can you pls fix the compile issue in the msm patch? Looks like that wasn't
properly compile-tested. For a howto, see:

https://blog.ffwll.ch/2016/02/arm-kernel-cross-compiling.html

and make sure MSM is enabled in the .config. You can configure the
cross-compiled kernel with e.g.

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig

Thanks, Daniel
