On Gen8+ this register is not priviledged and we want to use it in Mesa to implement a feature required by GPA called Null Hardware. The idea is to have the command parser turn 3DPRIMITIVE/GPGPU_WALKER into NOOPs. This patch just whitelists the bits that we need and that are currently not used by the kernel.
One thing I don't really know is whether is should be considered an issue with the current command parser and therefore be backported as a fix. It would certainly make things easier because we can't really detect the behavior from userspace.
