[PATCH 0/3] Various clean-up patches for GEM VRAM

[Thomas Zimmermann]

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.

Thomas Zimmermann (3):
  drm: Replace drm_gem_vram_push_to_system() with kunmap + unpin
  drm: Rename reserve/unreserve to lock/unlock in GEM VRAM helpers
  drm: Assert that BO is locked in drm_gem_vram_{pin,unpin}_locked()
