Subject: [PATCH 3.12 56/72] drm/radeon: narrow asic_init for virtualization

From: Alex Deucher <alexander.deucher@....com>

3.12-stable review patch.  If anyone has any objections, please let me know.

===============

commit 884031f0aacf57dad1575f96714efc80de9b19cc upstream.

Only needed on CIK+ due to the way pci reset is handled
by the GPU.
