Replacing drm_gem_vram_push_to_system() moves policy from drivers back to the memory manager. Now, unused BOs are only evicted when the space is required.
The lock/unlock-renaming patch aligns the interface with other names in DRM. No functional changes are done.
Finally, there's now a lockdep assert that ensures we don't call the GEM VRAM _locked() functions with an unlocked BO.
Patches are against a recent drm-tip and tested on mgag200 and ast HW.
