This series provides fixes for a couple of CONFIG_PREEMPT problems on Power: 1. The hpte_need_flush() function accesses per-CPU variables without protection. 2. The rtas_event_scan() function needs to use raw_smp_processor_id() to get a starting point to avoid debugging splats. There are probably a few more where these came from. ;-) Thanx, Paul
