This series of patches implemented to move i915 buddy allocator to drm root, and introduce new features include
- make drm_buddy_alloc a prime vehicle for allocation - TOPDOWN range of address allocation support - a function to free unused pages on contiguous allocation - a function to allocate required size comply with range limitations - cleanup i915 and amdgpu old mm manager references - and finally add drm buddy support to i915 and amdgpu driver modules
selftest patches will be sent in a separate series.
