Subject: -Wformat-trunctation with `make W=1`

Recently I'm trying to compile my (almost) x86_64_defconfig based kernel with
`make W=1` while having CONFIG_WERROR=y. With a handful of patches I was able
to achieve that with clang-18, however GCC 14.2.0 issues a lot of additional
warnings that are mostly related to -Wformat-truncation [1]. Any suggestions,
plans, comments on how to address them?
