[GIT PULL] array-bounds updates for v5.18-rc1

[Kees Cook]

Hi Linus,

Please pull these array-bounds updates for v5.18-rc1. Like the
FORTIFY_SOURCE tree, I was waiting for all the various other trees with
fixes to get merged. It looks like scsi was the last major tree I was
waiting on. 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].

Earlier build testing of this series merged against your tree didn't show
any new warnings, but as this option has been a bit of a whack-a-mole
over the last development cycle in -next, it's possible new cases
have appeared. We will remain vigilant. :) 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.

Thanks!

-Kees
