Subject: [PATCH v2 02/20] KVM: arm64: Remove duplicate configuration for SCTLR_EL1.{EE,E0E}
Date: Mon, 2 Feb 2026 18:43:11 +0000 [thread overview]
Message-ID: <20260202184329.2724080-3-maz@kernel.org> (raw)
In-Reply-To: <20260202184329.2724080-1-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")
Reviewed-by: Fuad Tabba <tabba@google.com>
