I was using some ad-hoc command line tricks, including objcopy -j .init.data build/multi_v7_defconfig/vmlinux /tmp/initdata nm initdata | sort -n | { read start b sym ; while read a b c ; do objdump -Dr --start-address=0x$start --stop-address=0x$a initdata > initdata.d/$sym ; start=$a ; sym=$c ; done } (some manual sorting to delete the files that have pre-initialized symbols) sum=0 ; nm /tmp/initdata | sort -n | { read start b sym ; while read a b c ; do test -e ../$sym && { echo $[0x$a - 0x$start]\ $sym ; sum=$[$sum + $[0x$a - 0x$start]] ; } ; start=$a ; sym=$c ; done ; echo $sum;} I'm sure there are better ways to do this, and the manual step I used at first was faulty.
