hm, why is that, and is it true for the full vmlinux as well, for a
reasonably large .config?
Do you get the size increase even if these two are enabled:
CONFIG_CC_OPTIMIZE_FOR_SIZE=y
CONFIG_OPTIMIZE_INLINING=y
?
i'd expect the opposite or same-size: given that an ugly
quasi-inlining macro is replaced with a shared, out of line function.
