---Problem Description---
In the cxl driver, the psl_fir_cntl register is set to the recommended value 
for a lab environment. This should be converted to use the recommended setting 
for a production environment.

Fix is in powerpc maintainer's tree and will find its way in 4.8-rc2;

cxl: Set psl_fir_cntl to production environment value
https://git.kernel.org/powerpc/c/c6d2ee09c2fffd3efdd31be2b2

However, though simple, the upstream patch won't apply cleanly to the
Xenial tree due to other patches merged in 4.8. So I'm attaching a
version of the patch which applies on Xenial
