In another branch of this thread Andrew said it's due to extra alignment 
padding (presumably with a view to improving execution speed) and Herbert Xu 
mentioned out-of-line conditional branch compilation, both of which sould 
reasonable to me.  They also sound like they could or should be trivially 
switchable.
