Is it not possible to just 'ifdef CONFIG_PARAVIT_FULL' the (ir)relevant
parts of paravirt.[ch] and paravirt_types.c?

Separating structures and files into pv and pvfull seems somewhat
arbitrary (.flush_tlb_others in patch 8 being a good example of one type
of guest deciding to use something that normally would be considered
part of a pvfull-type structure).
