[Bug 88227] Radeonsi: High GTT usage in Prison Architect large map

https://bugs.freedesktop.org/show_bug.cgi?id=88227

--- Comment #9 from James Harvey lothmordor@gmail.com --- Reverting the above commit against mesa git master did not solve the problem. Performed another bisection and got result:

commit b419c651fbbf3660d7b53623dfa2e5a4c9bd3b98 Author: Marek Olšák marek.olsak@amd.com Date: Wed Aug 20 23:53:40 2014 +0200

gallium/pb_bufmgr_cache: limit the size of cache

This should make a machine which is running piglit more responsive at times. e.g. streaming-texture-leak can easily eat 600 MB because of how fast it creates new textures.

Reverting this commit (to remove the cache limit) returned the game to full performance. Tested against git-ff1948a.
