Cover letter [PATCH powerpc 0/2] powerpc CONFIG_PREEMPT fixes
Hello!
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
