Subject: [PATCH v4 01/26] arm64: sysreg: Add missing ID_AA64ISAR[13]_EL1 fields and variants
Date: Wed, 14 Feb 2024 13:18:02 +0000 [thread overview]
Message-ID: <20240214131827.2856277-2-maz@kernel.org> (raw)
In-Reply-To: <20240214131827.2856277-1-maz@kernel.org>
Despite having the control bits for FEAT_SPECRES and FEAT_PACM,
the ID registers fields are either incomplete or missing.
Fix it.
