Subject: [PATCH 02/20] KVM: arm64: Remove duplicate configuration for SCTLR_EL1.{EE,E0E}
Date: Mon, 26 Jan 2026 12:16:36 +0000 [thread overview]
Message-ID: <20260126121655.1641736-3-maz@kernel.org> (raw)
In-Reply-To: <20260126121655.1641736-1-maz@kernel.org>
We already have specific constraints for SCTLR_EL1.{EE,E0E}, and
making them depend on FEAT_AA64EL1 is just buggy.
Fixes: 6bd4a274b026e ("KVM: arm64: Convert SCTLR_EL1 to config-driven sanitisation")
