The patch unfortunately broke gen4+ (more precisely: the unwritten abi
guarantee that userspace can tile buffers that don't have a complete last
tile row, as long as it promises not to touch it). Hence it got reverted.
It was just a enforcement check to prevent broken userspace from fooling
itself. The proper fix is to upgrade your userspace (libdrm +
xf86-video-intel).
[Aside: This only happens if you have new enough userspace that supports
relaxed tiling. Old userspace and new kernels are _not_ broken.]
Cheers, Daniel
