Config file for 4.17.3.

Hi there,

I'm experiencing some out-of-memory issues while running Cities:Skylines using
the amdgpu driver. Trying to run a new game cases a complete system-freeze
running any Kernel that runs the amdgpu driver instead of a rather old Kernel
using the amdgpu-pro driver. The memory is the system related main memory, not
the GPU memory.

System details:
I'm running Ubuntu Mate 16.04 with a custom build 4.17.3 Kernel (Find config
attached)
AMD FX-8350
32 GB RAM
Radeon RX470

Sample Main Memory usage.
Kernel 4.4 with amdgpu-pro driver    - RAM Usage after 1 Minute: 2.4 GB
Kernel 4.17.3 with amdgpu driver     - RAM Usage after 1 Minute: 13 GB
Kernel 4.16.18 with amdgpu driver    - RAM Usage after 1 Minute: 13 GB
Kernel 4.18.0-rc2 with amdgpu driver - RAM Usage after 1 Minute: 13 GB

I get similar results with running Stardew Valley (Factor two difference,
clearly measurable)

Find attached the config file for the 4.17.3 Kernel. Other kernels have been
build using this config file and the default suggestions for any unconfigured
parameter.

Greetings,
Felix
