Linux 4.0 Kernel Testing With AMD Radeon Graphics

The Radeon R9 290 looks like it regresses a bit on Linux 4.0, but there was a high deviation between the multiple test runs.

There's no changes noticed for the three graphics cards when testing on Linux 4.0.

Linux 4.0 is exciting for Radeon DP audio and better fan control support, but it doesn't appear there's any measurable performance changes.
