Subject: [PATCH v9 1/6] target-arm: kvm64 - introduce kvm_arm_init_debug()
Date: Thu, 12 Nov 2015 16:20:46 +0000	[thread overview]
Message-ID: <1447345251-22625-2-git-send-email-alex.bennee@linaro.org> (raw)
In-Reply-To: <1447345251-22625-1-git-send-email-alex.bennee@linaro.org>

As we haven't always had guest debug support we need to probe for it.
Additionally we don't do this in the start-up capability code so we
don't fall over on old kernels.
