Just a short update on this: I've pulled your patch into my series and
then thought I'd make a last pass over these and send out a new version
but then I started noticing a few more things that I thought I could
quickly clean up as well. One thing led to another and I'm now up to
double the number of patches. I still think it's worth doing, but
unfortunately it's become somewhat more complicated since it now touches
a couple more architectures and even some drivers (/dev/mem (!) and

I'm almost through sorting out the remaining issues I think, but it'll
take me another couple of days to rebase and squash patches and run some
build tests to verify that things don't break somewhere in the middle.

Oh, by the way: would you prefer that I keep your patch separate or
shall I just squash it into the one that has the major asm-generic/io.h
