Subject: [PATCH v1 06/11] powerpc/pseries: lparcfg don't include slb_size line in radix mode
Date: Sat, 16 Oct 2021 01:46:19 +1000 [thread overview]
Message-ID: <20211015154624.922960-7-npiggin@gmail.com> (raw)
In-Reply-To: <20211015154624.922960-1-npiggin@gmail.com>
This avoids a change in behaviour in the later patch making hash
support configurable. This is possibly a user interface change, so
the alternative would be a hard-coded slb_size=0 here.
