--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I am not so sure this is wanted. GCC assumes a flat memory system for stack and
normal memory accesses .

This fix is not simple really because addresses don't need to be just in EBP
really and even can be stored off into stack memory and then loaded back.
It seems like there must be a better way of implementing this inside your
kernel as a flat memory system between stack and data segments is not going to
change because it would add a very complex tracking.
