Subject: [PATCH v4 01/36] arm64: Drop SKL0/SKL1 from TCR2_EL2
Date: Wed,  9 Oct 2024 19:59:44 +0100	[thread overview]
Message-ID: <20241009190019.3222687-2-maz@kernel.org> (raw)
In-Reply-To: <20241009190019.3222687-1-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.
