pr_warn_ratelimit() please. There is no point printing this all the time
if nobody reads the messages.

It would be nice if the module name could be the same for arm32 and arm64,
and I don't know if we want to rename swp_emulate.c to v7_obsolete.c
on arm32.
Other than that, I have no opinion on the specific name of the module
or the option.
