Subject: [PATCH v4 1/8] arm64/mte: Move shift from definition of TCF0 enumeration values
Date: Tue, 19 Apr 2022 11:43:22 +0100	[thread overview]
Message-ID: <20220419104329.188489-2-broonie@kernel.org> (raw)
In-Reply-To: <20220419104329.188489-1-broonie@kernel.org>

In preparation for automatic generation of SCTLR_EL1 register definitions
move the shifting of the enumeration values for the TCF0 field from the
defines in the header to the point where they are used.
