More Radeon/AMDGPU Fixes Line-Up For Linux 4.3

With having more time until the Linux 4.3 merge window, Alex Deucher of AMD sent in more changes for the Radeon and AMDGPU DRM kernel drivers, albeit it's mostly fixes.

The Linux 4.3 kernel already is set to prominently add Fiji GPU support and AMDGPU scheduler support as the major AMD graphics highlights of this next kernel cycle. Sent in today were more fixes for cleaning up both the Radeon (for most AMD GPUs out there) and AMDGPU (for Carrizo / Tonga / Fiji / and future hardware).

This latest pull request has DisplayPort fixes for both drivers, an IH ring fix for Tonga/Fiji, a number of GPU scheduler fixes, and other random corrections. More details via this pull request.

Stay tuned for a lot of tests featuring Mesa 11.0 + DRM-Next on Phoronix in the days ahead, including the first open-source Radeon R9 Fury performance numbers.
