Kernel config

Trying to couple mainline amdgpu driver with opencl from amdgpu-pro (installed
via Gentoo dev-libs/amdgpu-pro-opencl package) to make darktable use opencl
again.  Clinfo and apps see the opencl but when trying to create a command
queue driver returns CL_OUT_OF_HOST_MEMORY. The same behavior is reported on
Ubuntu 16.04.3 as seen here https://redmine.darktable.org/issues/11702

kernel 4.12.0-pf7 
xorg-server-1.19.3
libdrm-2.4.82
xorg-1.19.3
x11-drivers/xf86-video-amdgpu-1.3.0
dev-libs/amdgpu-pro-opencl-17.30.465504
