Can you add a high level comment to entry.S what paravirt mode
is all about and perhaps a quick cheat sheet on the macros?

That's ugly. Can't you call different wait functions for that case instead?

You could probably avoid a lot of ifdefs by strategic use of
__attribute__((weak))

This is probably a good candidate for rename to native + wrapper
macros too. Otherwise we'll always have to hack two different
places later.
