From 928c25d14f76ff537bd56f135b91cf681dee326b Mon Sep 17 00:00:00 2001
From: Keith Whitwell <keith@tungstengraphics.com>
Date: Tue, 22 Apr 2003 12:07:24 +0000
Subject: Move the excitingly named DRM(flush_block_and_flush) and friends to  
   gamma-specific code. Fix templates so i8x0 drivers don't have to define
 __HAVE_DMA_WAITLIST.
