At least for ARM64 kernels compiled with the crosstoolchain from
Debian/stretch or with the toolchain from kernel.org the line number is not
decoded correctly by 'decode_stacktrace.sh':
$ echo "[ 136.513051] f1+0x0/0xc [kcrash]" | \
CROSS_COMPILE=/opt/gcc-8.1.0-nolibc/aarch64-linux/bin/aarch64-linux- \
./scripts/decode_stacktrace.sh /scratch/linux-arm64/vmlinux \
/scratch/linux-arm64 \
/nfs/debian/lib/modules/4.20.0-devel
[ 136.513051] f1 (/linux/drivers/staging/kcrash/kcrash.c:68) kcrash
If addr2line from the toolchain is used the decoded line number is correct:
[ 136.513051] f1 (/linux/drivers/staging/kcrash/kcrash.c:57) kcrash
