Side note #1, these parameters are for testing and debugging only, and
it is recommended to stick to the platform specific defaults. We'll soon
start tainting the kernel when these parameters have been set.

Side note #2, starting from v3.15 the extra i915_ prefix has been
removed from i915.i915_enable_rc6 and i915.i915_enable_fbc parameters to
make them i915.enable_rc6 and i915.enable_fbc.


BR,
Jani.
