Hi Linus,

Please pull these scattered buffer and array bounds fixes for v5.18-rc1.
These are a handful of fixes that I've been carrying in -next in
preparation for the coming memcpy improvements and the enabling of
-Warray-bounds globally. There are additional similar fixes in other
maintainer's trees, but these ended up getting carried by me. :)

Thanks!

-Kees
