        <pre>It looks like this error is earlier than
e9fea5747d2b3dbff47a8790c1cc4d7af80051d6.
I try to apply this patch on earlier commit and try to find any good commit,
but patch fails.
patching file drivers/gpu/drm/i915/i915_reg.h
Hunk #1 FAILED at 748.
Hunk #2 FAILED at 824.
2 out of 2 hunks FAILED -- saving rejects to file

patching file drivers/gpu/drm/i915/intel_ringbuffer.h
Hunk #1 succeeded at 35 with fuzz 2 (offset 2 lines).

So I am not sure it is regression.</pre>
