This commit which first appeared in 3.15-rc1 causes hangs on Bonaire:

drm/radeon: use normal BOs for the page tables v4
No need to make it more complicated than necessary,
just allocate the page tables as normal BO and
flush whenever the address change.
v2: update comments and function name
v3: squash bug fixes, page directory and tables patch
v4: rebased on Mareks changes
Signed-off-by: Christian König <christian.koenig at amd.com>
Reverting the commit gives me a lot of merge conflicts.
The simplest way to reproduce the hangs is to run piglit with these parameters:
Some of the tests allocate a lot of MSAA textures and the tests also
run in parallel, which creates a lot of memory pressure and probably
causes buffer evictions.
Any idea what is wrong with it?
