For patches 1-4: Reviewed-by: Paulo Zanoni <paulo.r.zanoni at intel.com>
But for patch 4, can't we try to create a new intel_rps.c and move
stuff there, instead of keeping them in i915_irq.c? I kinda like the
idea of files containing single features... Anyway, we can do this in
yet-another patch.
For patches 5-6: the addition of gen9_disable_rps() and
gen9_enable_rps() kinda broke these patches...
