This series refactors i915's stolen memory region to use ttm.
v2: handle disabled stolen similar to legacy version. relying on ttm to fail allocs works fine, but is dmesg noisy and causes testing dmesg warning regressions.
v3: rebase to latest drm-tip. fix v2 code refactor which could leave a buffer pinned. locally passes fftl again now.
Robert Beckett (5): drm/i915: instantiate ttm ranger manager for stolen memory drm/i915: sanitize mem_flags for stolen buffers drm/i915: ttm move/clear logic fix drm/i915: ttm backend dont provide mmap_offset for kernel buffers drm/i915: stolen memory use ttm backend
