Subject: [PATCH v4 5/9] KVM: arm64: Handle CSSIDR2_EL1 and SMIDR_EL1 in a generic way
Date: Thu, 8 Jan 2026 17:32:29 +0000 [thread overview]
Message-ID: <20260108173233.2911955-6-maz@kernel.org> (raw)
In-Reply-To: <20260108173233.2911955-1-maz@kernel.org>
Now that we can handle ID registers using the FEAT_IDST infrastrcuture,
get rid of the handling of CSSIDR2_EL1 and SMIDR_EL1.
