commit b1da8d89c8d13e3f0254d69c639c7f66c10e4175

igt/prime_mmap_coherency: Reorder cache flushes to avoid excess pressure
Flush the secondary buffer from the cpu cache before dirtying the cache
for the primary to ensure a better chance of the primary buffer
remaining in cache, causing the incoherency.
