[PATCH 0/4] Merge VRAM MM and GEM VRAM source files
VRAM MM and GEM VRAM are only used with each other. This patch set
moves VRAM MM into GEM VRAM source files and cleans up the helper's
public interface.
Thomas Zimmermann (4):
drm/vram: Move VRAM memory manager to GEM VRAM implementation
drm/vram: Have VRAM MM call GEM VRAM functions directly
drm/vram: Unexport internal functions of VRAM MM
drm/vram: Unconditonally set BO call-back

[PATCH v2 0/4] Merge VRAM MM and GEM VRAM source files
VRAM MM and GEM VRAM are only used with each other. This patch set
moves VRAM MM into GEM VRAM source files and cleans up the helper's
public interface.
Version 2 of the patch set doesn't contain functional changes. I'm
reposting due to the rebasing onto the debugfs patches.
v2:
* updated for debugfs support
* fixed typos in comments
Thomas Zimmermann (4):
drm/vram: Move VRAM

[PATCH v2 00/17] Share TTM code among DRM framebuffer drivers
Several simple framebuffer drivers copy most of the TTM code from each
other. The implementation is always the same; except for the name of
some data structures.
As recently discussed, this patch set provides generic memory-management
code for simple framebuffers with dedicated video memory. It further
converts the respective drivers to the generic code. The shared code
is basically the same
