[RFC PATCH 0/3] drm/helpers: Make the suballocation manager drm generic.

The suballocation manager itself is not dependent on any implementation detail,
and can be made generic. I want to potentially use it inside i915, as it looks
like a clean implementation to do so. :)

Looking for feedback and some testing, as I don't have a amdgpu/radeon myself.
Only compile tested so far, so some stupid bugs may remain.

Maarten Lankhorst (3):
  drm: Extract amdgpu_sa.c as a generic suballocation helper
  drm/amd: Convert amdgpu to use suballocation helper.
  drm/radeon: Use the drm suballocation manager implementation.
