Merge branch 'drm-next-4.14' of git://people.freedesktop.org/~agd5f/linux into drm-next
- Stop reprogramming the MC, the vbios already does this in asic_init - Reduce internal gart to 256M (this does not affect the ttm GTT pool size) - Initial support for huge pages - Rework bo migration logic - Lots of improvements for vega10 - Powerplay fixes - Additional Raven enablement - SR-IOV improvements - Bug fixes - Code cleanup * 'drm-next-4.14' of git://people.freedesktop.org/~agd5f/linux: (138 commits) drm/amdgpu: fix header on gfx9 clear state drm/amdgpu: reduce the time of reading VBIOS drm/amdgpu/virtual_dce: Remove the rmmod error message drm/amdgpu/gmc9: disable legacy vga features in gmc init drm/amdgpu/gmc8: disable legacy vga features in gmc init drm/amdgpu/gmc7: disable legacy vga features in gmc init drm/amdgpu/gmc6: disable legacy vga features in gmc init (v2) drm/radeon: Set depth on low mem to 16 bpp instead of 8 bpp drm/amdgpu: fix the incorrect scratch reg number on gfx v6 drm/amdgpu: fix the incorrect scratch reg number on gfx v7 drm/amdgpu: fix the incorrect scratch reg number on gfx v8 drm/amdgpu: fix the incorrect scratch reg number on gfx v9 drm/amd/powerplay: add support for 3DP 4K@120Hz on vega10. drm/amdgpu: enable huge page handling in the VM v5 drm/amdgpu: increase fragmentation size for Vega10 v2 drm/amdgpu: ttm_bind only when user needs gpu_addr in bo pin drm/amdgpu: correct clock info for SRIOV drm/amdgpu/gmc8: SRIOV need to program fb location drm/amdgpu: disable firmware loading for psp v10 drm/amdgpu:fix gfx fence allocate size ...
