Subject: drm/radeon: fix init ordering for r600+
From: Alex Deucher <alexander.deucher@xxxxxxx>
commit e5903d399a7b0e5c14673c1206f4aeec2859c730 upstream.
The vram scratch buffer needs to be initialized
before the mc is programmed otherwise we program
0 as the GPU address of the default GPU fault
page. In most cases we put vram at zero anyway and
reserve a page for the legacy vga buffer so in practice
this shouldn't cause any problems, but better to make
it correct.
