[Mesa-dev] [PATCH 4/9] panfrost: Flush when using transform feedback

[Alyssa Rosenzweig]

This is a huge hack to workaround incomplete BO flushing logic, but it's
enough for the dEQP transform feedback tests, and doing the resource
management to get this right is out-of-scope for this patch series.
