If an rtas node doesnt exist, we continually fall out of pSeries_probe_hypertas early and never get to the MMU init code. While pseries without RTAS is an illegal combination, the way we currently fail is a pain to track down, and can happen if your flattened device tree code has issues (like mine did :). With the following patch we init the MMU, come up and print some warnings about RTAS not existing, instead of looping on 0x400 exceptions.
