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). -boris
