However you weren't doing in-kernel relocations.. ioremap/iounmap are both causing flushes... so we would need to keep ioremapped cached copies of the batchbuffer bo around.. which wastes vmalloc space.. or use kmap and flush once per buffer.. my previous attempts to use kmap without flushing failed badly..
