--- Comment #5 from Richard Earnshaw <rearnsha at gcc dot gnu.org> ---
Yeah, all the changes are in the linux kernel module.  It's only one component
of the benchmark (though probably the largest).

Adding -fgnu89-inline is also sufficient to fix the code size regression.

Increased compile times are (probably) just a side effect of generating the
additional code.
