H A Di915_gem_gtt.hf6b9d5ca Thu Aug 04 01:52:23 CDT 2016 Chris Wilson <chris@chris-wilson.co.uk> drm/i915: Split early global GTT initialisation

Initialising the global GTT is tricky as we wish to use the drm_mm range
manager during the modesetting initialisation (to capture stolen
allocations from the BIOS) before we actually enable GEM. To overcome
this, we currently setup the drm_mm first and then carefully rebind
them.

v2: Fixup after rebasing
v3: GGTT initialisation needs to be split around kicking out conflicts
v4: Restore an old UMS BUG_ON(mappable > total) as a DRM_ERROR plus
fixup of probe results.
