Subject: [PATCH] drm/ttm: Do not add non-system domain BO into swap list
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

BO would be added into swap list if it is validated into system domain.
If BO is validated again into non-system domain, say, VRAM domain. It
actually should not be in the swap list.
