From ed017d9fb17af3162f5acf922eb5731c541e1f3a Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Wed, 2 Sep 2009 09:41:13 +1000 Subject: [PATCH] drm: fix drm_cache.c for arch with no support. This produces a warn on for architectures where this gets called but we don't have a cache flushing implementation suitable.
