This is the right thing, incidentally. The _raw() functions are
supposed to take a guest physical address (as an integer), where
the _p() ones take a host void*. However the implementation means
you can get away with misusing the _raw() function where you meant
the _p() function provided your code is only built for system
emulation, because the macro's casts mean the compiler won't
call you it. (We should probably try to clean up some of the
misuses.)
