Merge tag 'hardening-v6.14-rc1-fix1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull hardening fixes from Kees Cook:
"This is a fix for the soon to be released GCC 15 which has regressed
its initialization of unions when performing explicit initialization
(i.e. a general problem, not specifically a hardening problem; we're
just carrying the fix).
Details in the final patch, Acked by Masahiro, with updated selftests
to validate the fix"
* tag 'hardening-v6.14-rc1-fix1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux:
kbuild: Use -fzero-init-padding-bits=all
stackinit: Add union initialization to selftests
stackinit: Add old-style zero-init syntax to struct tests
