   Why must the hook be implemented in xc_ia64_hvm_build.c?  It's
definitely the obvious candidate, but we could also make it an
architecture dependent static inline in something like vl.h, where the
overloading occurs now.  The overloading is a nice trick, but a context
dependent function like that seems prone to errors to me.  Thanks,

        Alex
