Come to think of it, if we/I succeed in adding lockdep checking in _raw, then
we can just keep the current APIs and not delete anything. And we can have
_raw_notrace skip the lockdep checks. The sparse check question would still
be an open one though, since _raw doesn't do sparse checks at the moment
unlike _raw_notrace as Steve pointed.

Thanks,
