Subject: [PATCH 02/28] arm64: Update ID_AA64MMFR4_EL1 description to 2026-03 JSON release
Date: Thu,  2 Jul 2026 17:02:22 +0100	[thread overview]
Message-ID: <20260702160248.1377250-3-maz@kernel.org> (raw)
In-Reply-To: <20260702160248.1377250-1-maz@kernel.org>

ID_AA64MMFR4_EL1 has gained a few fields and enum values in the past
few months, so resync its definition with the 2026-03 JSON release.
