I wonder if this'll generate smaller and better code than _both_ the
other atomic_read_volatile() variants. Would need to build allyesconfig
on lots of diff arch's etc to test the theory though.

I'm sure it would be a tiny effect.

This whole thread is arguing about effects that are quite
insignificant.

Hmm, the fact that this thread became what it did, probably means that
most developers on this list do not mind thinking/arguing about effects
or optimizations that are otherwise "tiny". But yeah, they are tiny
nonetheless.
