Geode still builds fine. include/lib.h includes a new function, cycles(), which is a u64 and architecture-defined. (Thanks, Plan 9, for a sensible idea). All rdtsc removed in favor of cycles() All other changes are k8 specific. None of these changes adversely impact existing platforms AFAICT. Goal is that by 31/8/8, we're testing on simnow.
