Pull hardening updates from Kees Cook:
 "As usual, it's scattered changes all over. Patches touching things
  outside of our traditional areas in the tree have been Acked by
  maintainers or were trivial changes:

   - loadpin: remove unsupported MODULE_COMPRESS_NONE (Arulpandiyan
     Vadivel)

   - samples/check-exec: Fix script name (Mickaël Salaün)

   - yama: remove needless locking in yama_task_prctl() (Oleg Nesterov)

   - lib/string_choices: Sort by function name (R Sundar)

   - hardening: Allow default HARDENED_USERCOPY to be set at compile
     time (Mel Gorman)

   - uaccess: Split out compile-time checks into ucopysize.h

   - kbuild: clang: Support building UM with SUBARCH=i386

   - x86: Enable i386 FORTIFY_SOURCE on Clang 16+

   - ubsan/overflow: Rework integer overflow sanitizer option

   - Add missing __nonstring annotations for callers of
     memtostr*()/strtomem*()

   - Add __must_be_noncstr() and have memtostr*()/strtomem*() check for
     it

   - Introduce __nonstring_array for silencing future GCC 15 warnings"
