However ... what happens to functions calling __pa that are called from 
boot time and run time code?
I've actually only run into one of those so far that I know of, and that
was on ppc64 (i386 had none that I found).  In that one case, I used an
if(unlikely()) to optimize for the run-time one.  There might be more,
but I think they're rare enough to just code it with an if() in each
case.
