For the page table format, the PAE types and macros could be redefined with a prefix, and then aliased to the ones used in kernel when "options PAE" is defined. kvatop/pa2off functions could have access to both macros/typedefs, by just having pae_ prefixed in front (pae_pl*_pi, pae_pd_entry_t, and so on). It becomes a matter of calling the proper code within kvm(3), by checking if PAE was enabled within the kernel dump (through kvm_nlist, for example). -- Jean-Yves Migeon jeanyves.mig...@free.fr
