History may not be relevant here. It could be that in the past GCC was simply not able to track the state of the control bit when generation the code. As such the compiler had to insert the explicit instructions to reset the bit even if it was known that they were not necessary from ABI point of view.

GCC 4.3.0 exposes a kernel bug Posted Mar 9, 2008 3:37 UTC (Sun) by dlang (✭ supporter ✭, #313) [Link] the history is very relevant. you are listing a third option (very similar to the second one I listed above) knowing which of these is correct (or if there is a fourth that is correct) is significant in evaluating what needs to change.
