Patch against 2.6.15. From: Alan Hourihane Signed-off-by: Dave Jones commit 168678233ca45af3f74fef60c4265fa5dd217e29 Author: akpm@osdl.org Date: Fri Jan 13 15:51:02 2006 -0800 [AGPGART] Semaphore to Mutex conversion. Semaphore to mutex conversion. The conversion was generated via scripts, and the result was validated automatically via a script as well.
