Subject: [v3 4/5] arm64: kvm: add cpu reset at module exit
Date: Thu,  2 Apr 2015 14:40:15 +0900	[thread overview]
Message-ID: <1427953216-11737-5-git-send-email-takahiro.akashi@linaro.org> (raw)
In-Reply-To: <1427953216-11737-1-git-send-email-takahiro.akashi@linaro.org>

This patch doesn't enable kvm to be built as a module, but is
a prerequisite when kvm is transformed to be module-capable.
