6.8-stable review patch.  If anyone has any objections, please let me know.

[ 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.
