[ Upstream commit b0b13d532105e0e682d95214933bb8483a063184 ]
Make SVM BOs more likely to get evicted than other BOs. These BOs opportunistically use available VRAM, but can fall back relatively seamlessly to system memory. It also avoids SVM migrations evicting other, more important BOs as they will evict other SVM allocations first.
