Subject: [PATCH v2 1/2] arm64/esr: Use GENMASK() for the ISS mask
Date: Mon, 08 May 2023 22:50:09 +0900 [thread overview]
Message-ID: <20230417-arm64-iss2-dabt-decode-v2-1-84e1c1463d30@kernel.org> (raw)
In-Reply-To: <20230417-arm64-iss2-dabt-decode-v2-0-84e1c1463d30@kernel.org>
We express the mask for ESR_ELx.ISS in a non-standard manner, not using
the standard helpers. In preparation for adding decode for ISS2 convert to
use GENMASK(). No functional change.
