Subject: [PATCH 3/4] kvm/arm64: simplify CC instrumentation opt-out
Date: Mon, 16 Oct 2017 14:24:39 +0100 [thread overview]
Message-ID: <20171016132440.38098-4-mark.rutland@arm.com> (raw)
In-Reply-To: <20171016132440.38098-1-mark.rutland@arm.com>
Now that we can opt out of all instrumentation with a single option,
make use of this in the KVM hyp code. Hopefully, this will also avoid
fragility as new options are introduced.
