You don't *have* to squash them.

We like to preserve bisectability, but it's not a 100% hard requirement.

Someone trying to bisect through those patches can always turn off
-Werror with PPC_DISABLE_WERROR. But they probably can just skip them
because they just add new code that's not called yet.

So I won't object if you send them as-is.

cheers
