Sorry about this.

Is seems any arch without its own __set_fixmap may be adversely
affected.

I can't easily stub __set_fixmap as it's not implemented as a macro.

I think we can stick with a macro and remove 'addr', by returning the
result of the expression directly. As fix_to_virt gave us an unsigned
long I think the types should line up (i.e. the result will be at least
unsigned long wide).

Arnd, would you be happy with the below patch instead? 

It builds fine for arm, arm64, mips, and tilegx in local testing.

Thanks,
Mark.
