good perf gallium hud on 4.14 kernel.

R9285 Tonga, Compared to older kernels I have a perf regression with latest
4.14.0-rc3 based and previous 4.13-rc5 based agd5f 4.15-wip kernels.

This doesn't seem to affect other things like xonotic or unigine demos.

Issue =3D on fixes 4.14 and other older kernels I've tried, the game is OK =
ish
perf wise, 25-60 fps.

On 4.15-wip its 10fps. Using HUD one obvious difference is that the slow ca=
se
is only mostly using one cpu core, on a good kernel all 4 of my old phenom =
2 x4
are used - possible red herring of course, I'll upload some screenshots.

The game is pre-alpha and doesn't always render properly - but it was vague=
ly
playable fps wise until this kernel.
