This patchset adds on the previous one, merging the suggestions made mainly by Gleb, Peter and Marcelo. SCHEDSTATS is now used when available to provide information about time spent on the runqueue for the cpu threads. Information to/from the guest is obtained using *_cached() functions, as suggested by Gleb. On the guest side, the two "prev_steal_time" variables are colapsed into a single one. Steal time accounting is also done inside update_rq_clock().
