Well please keep in mind that each patch on its own should not break anything.
Especially patches #1, #2, #3 and #10 look like they need to be squashed together to cleanly move the i915 code into a common place.

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.
