I*think* the patch below is all we need, as well as some tweaking of patch 2, are you able to test and repost?
Enabling the fallback flush always looks a bit dodgy but do_rfi_flush_fixups will overwrite the jump so long any other fixup is enabled.
I agree; the 'Using fallback displacement flush' message is misleading (is the system slower/fallback or not? Ô_o) The suggested patch is definitely more contained within pseries, but the informational part seemed dodgy IMHO too. So I wrote something with a new function parameter to force the init of the fallback flush area (true in pseries, false in powernv). Not that contained, but it seemed to convey the intent here in a clear way. That's v2, just sent. cheers, Mauricio
