Subject: [PATCH v3 01/24] arm64: Drop SKL0/SKL1 from TCR2_EL2
Date: Wed, 11 Sep 2024 14:51:28 +0100 [thread overview]
Message-ID: <20240911135151.401193-2-maz@kernel.org> (raw)
In-Reply-To: <20240911135151.401193-1-maz@kernel.org>
Despite what the documentation says, TCR2_EL2.{SKL0,SKL1} do not exist,
and the corresponding information is in the respective TTBRx_EL2. This
is a leftover from a development version of the architecture.
This change makes TCR2_EL2 similar to TCR2_EL1 in that respect.
