Subject: [PATCH v2 5/7] perf arm-spe: Remove the unused 'midr' field
Date: Sat, 14 Sep 2024 23:08:59 +0100	[thread overview]
Message-ID: <20240914220901.756177-6-leo.yan@arm.com> (raw)
In-Reply-To: <20240914220901.756177-1-leo.yan@arm.com>

The 'midr' field is replaced by the MIDR values stored in metadata (per
CPU wise). Remove the 'midr' field as it is no longer used.
