Yeah, still there for `kernel/kallsyms.c`:

Though in reality seems to not hurt operation of kernels - built with a GCC
with just `--checking=release` - like the v6.17-rc1 with which my rx2800 i2
recently bootstrapped and testsuite-tested GCC 15.2.0 for 10+ hours combined.
The lab room is still cooling down... ;-)
