You're right that it would probably be slow, but I'm hoping that most
platforms have a sane way to address this problem.  I know, for
example, that the mips64 port can use a simple 'sync' instruction to
accomplish the same thing.  Thanks for applying the patch.  Any ideas
on how I might go about getting this macro accepted by other platform
maintainers so that we can sprinkle it into drivers as necessary?

Thanks,
Jesse
