From b47cf66f315a258c458ed4345c443dba396fb787 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Thu, 4 Nov 2010 18:41:50 +0100 Subject: [PATCH] intel-gtt: drop dcache support for i830 and later i830_check_flags already disallows it, so no need to implement it in the write_entry function. Seems to be a remnant from i810 support.
