[PATCH 0/2] Small fixes around cacheflush.h

Hi all,

These two patches are the culmination of the small discussion here:

https://lore.kernel.org/lkml/CAMuHMdVSduTOi5bUgF9sLQdGADwyL1+qALWsKgin1TeOLGhAKQ@mail.gmail.com/ (local)

I have fallen behind on fixing issues so sorry for not sending these
sooner and letting these warnings slip into mainline. Please let me know
if there are any comments or concerns. They are two completely
independent patches so if they need to be routed via separate trees,
that is fine. It was just easier to send them together since they are
dealing with the same problem.

Cheers,
Nathan
