The idea is _NOT_ that you go look for references to the paravirt_ops

patching up indirect calls and crap like that.  Just say no...

Instead you get rid of paravirt ops completely, and you call functions
whose symbol name will not resolve in the initial kernel link.
  

Yeah, I came to that conclusion after thinking about it for a while. 
Thanks for the pointer to the sparc stuff; it looks very interesting.
