FBC has too many corner cases that we don't currently deal with, so
disable it by default so we can enable more important features like RC6,

It's a bit weird to ...

+unsigned int i915_enable_fbc = 0;
+module_param_named(i915_enable_fbc, i915_enable_fbc, int, 0600);
+

... disable fbc by default ...

+       if (!i915_enable_fbc) {
+               DRM_DEBUG_KMS("fbc disabled manually\n");
+               dev_priv->no_fbc_reason = FBC_MANUAL_DISABLE;
+               goto out_disable;
+       }

... and then claim the user is to blame.
