Subject: [PATCH v2 05/10] ppc/spapr: Adjust ibm,pa-features for POWER9
Date: Tue, 12 Mar 2024 23:14:14 +1000	[thread overview]
Message-ID: <20240312131419.2196845-6-npiggin@gmail.com> (raw)
In-Reply-To: <20240312131419.2196845-1-npiggin@gmail.com>

"MMR" and "SPR SO" are not implemented in POWER9, so clear those bits.
HTM is not set by default, and only later if the cap is set, so remove
the comment that suggests otherwise.
