Merge tag 'array-bounds-v5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull array-bounds updates from Kees Cook:
 "This enables -Warray-bounds and -Wzero-length-bounds, now that the
  many bug fixes have landed all over the place in the kernel, and in
  GCC itself[1].

  A couple fixes[2] for known corner-case issues currently live in my
  "pending-fixes" tree which I'm expecting to send next week if other
  maintainers still haven't picked them up.

  I'm also expecting we can enable -Wstringop-overflow next cycle, as
  there are only a few stragglers[3], but it might even be possible for
  this release"
