3.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Alex Deucher <alexander.deuc...@amd.com>
commit 6fab3febf6d949b0a12b1e4e73db38e4a177a79e upstream.
For r6xx+ asics. This mirrors the behavior of pre-r6xx
asics. We need to program the MC even if something
else in startup() fails. Failure to do so results in
an unusable GPU.
Based on a fix from: Mark Kettenis <kette...@openbsd.org>
Signed-off-by: Alex Deucher <alexander.deuc...@amd.com>
[ rebased for 3.10 and dropped the drivers/gpu/drm/radeon/cik.c
bit as it's 3.11 specific code / tmb ]
