i also tried a config with the best size settings (disabling
FRAME_POINTER, enabling CC_OPTIMIZE_FOR_SIZE), and this gives:

text data bss dec filename
20777768 6076042 3081864 29935674 vmlinux.x32.size.before
20748140 6076178 3081864 29906182 vmlinux.x32.size.after

or a 34.8 bytes win per callsite (29K total).
