According to wikipedia:

"In digital photography, the raw file plays the role that photographic film plays in film photography. Raw files thus contain the full resolution (typically 12- or 14-bit) data as read out from each of the camera's image sensor pixels."

This would imply no noise reduction in the RAW file. Simply data from each photosensitive site. Covered with a RGB filter then light converted to electrical charge and quantified.

They all apply NR but not to this degree. It certainly seems to be worse with the X-E2 in my experience. It doesn't help that my wife has freckles...

Might be the definition but the reality I suspect is something else.  For example the engine that reads the values does some signal to noise processing during the read operation.  I suspect there is some other intelligent stuff going on to extrapolate or interpolate sensor values from surrounding sensors.  One specific example, would be mapping out bad pixels.
