This change fixed a hang for me when running the piglit test
max-texture-size with the radeon driver on Kaveri.
However, there's still a similar hang left when letting the piglit test
tex3d-maxsize run concurrently with other tests (running tex3d-maxsize
alone doesn't hang, but fails due to running out of GPU memory; that's a
recent radeonsi regression). There are
[TTM] Buffer eviction failed
messages in dmesg shortly before the hang.
I haven't seen such hangs with older kernels. Any ideas offhand what the
problem could be? If not, I'll try bisecting.
