Merge tag 'hardening-v6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull hardening updates from Kees Cook:
 "As has become normal, changes are scattered around the tree (either
  explicitly maintainer Acked or for trivial stuff that went ignored):

   - Carve out the new CONFIG_LIST_HARDENED as a more focused subset of
     CONFIG_DEBUG_LIST (Marco Elver)

   - Fix kallsyms lookup failure under Clang LTO (Yonghong Song)

   - Clarify documentation for CONFIG_UBSAN_TRAP (Jann Horn)

   - Flexible array member conversion not carried in other tree (Gustavo
     A. R. Silva)

   - Various strlcpy() and strncpy() removals not carried in other trees
     (Azeem Shaikh, Justin Stitt)

   - Convert nsproxy.count to refcount_t (Elena Reshetova)

   - Add handful of __counted_by annotations not carried in other trees,
     as well as an LKDTM test

   - Fix build failure with gcc-plugins on GCC 14+

   - Fix selftests to respect SKIP for signal-delivery tests

   - Fix CFI warning for paravirt callback prototype

   - Clarify documentation for seq_show_option_n() usage"
