Uh, sorry about this...

Nathan Chancellor just pointed out that my commit "rwonce: handle
KCSAN like KASAN in read_word_at_a_time()" breaks the arm64 build when
LTO is enabled (<https://lore.kernel.org/all/20250326203926.GA10484@ax162/>).
I just posted a patch that undoes the buggy part of my patch at
<https://lore.kernel.org/r/20250326-rwaat-fix-v1-1-600f411eaf23@google.com>.

@Linus: Sorry for throwing a spanner in the works here... maybe you
should only pull up to the commit before mine (luckily mine's the last
in the stack, and it's not important), or wait for Arnd to give his
opinion.
