As I said in the commit log, it doesn't seem to make sense to export
them when they are trivial enough to be static inline, since it
avoids having them pollute the /proc/kallsyms namespace.

It is almost like having basic inb/outb as functions vs inline; it
just doesn't make sense to me.

However, if you are determined to rewrite the patch in another way,
please add the customary reported-by line.

Thanks,
Paul.
