We prepared a patch series without patches 11, 22 (both were dropped),
37, 40 (it has a NACK from Curro) and 56. Our idea was to push the
patch series once we check there is no piglit regressions.

We got 0 piglit regressions on ILK, SNB, IVB, HSW and BDW, the latter
with the extension enabled with the environment variable.

Sadly, on SKL we had regressions (including GPU hangs) only if we
*enable* the arb_gpu_shader_fp64 extension. Those regressions are
fixed by patch 40 but we need still to investigate why they are happening.

For that reason, we have not pushed anything yet. Tomorrow we will
investigate why we have those regressions only on SKL and which tests
are affected.

JFTR, if we disable the extension on SKL (i.e. we don't set the
environment variable), we have 0 piglit regressions on that generation.

Thanks,

Sam
