[Mesa-dev] [PATCH] radeon, r200: fix buffer validation after CS flush

[Marek Olšák]

From: Marek Olšák <marek.olsak at amd.com>

This validates all bound buffers (CB, ZB, textures, DMA) at the beginning
of CS. This fixes "bo->space_accouned" assertion failures.

Tested by: Jochen Rollwagen <joro-2013 at t-online.de>
