Subject: [PATCH 0/2] ERAT invalidation fixes
Date: Mon, 27 Aug 2018 13:03:00 +1000 [thread overview]
Message-ID: <20180827030302.17541-1-npiggin@gmail.com> (raw)
First one is a real bug-fix for POWER8 and earlier CPUs, second I'm
not exactly sure how POWER9's ERAT behaves in this situation but it
seems to match what we do in other places.
Thanks,
Nick
